The 1968 Motor Show Crusader had an upright exhaust but like the Buffalo just as many had under bumper exhausts too, the UK did take longer to use this system compared to other countries especially the USA. Franky.

The 16 ‘M’ reg. (1973 -74) AEC Mandators Turners had for the British Sugar contract had upright exhaust stacks. it was a requirement of the contract and quite enlightened thinking for the time. The reason being to keep exhaust fumes away from the driver when he was blowing off the tank.The subsequent makes on that contract also had upright exhausts, Volvo FL10, DAF 85, ERF E10
Whereas, when I was on contract to British Sugar, it was stipulated that the driver had to be at the rear of the vehicle, within reach of the comtrols when blowing the load off.

Which is still the instruction to powder tank drivers and it is carried out to the letter by our drivers. I have seen drivers of other hauliers sitting in the cab whilst the tank is discharging… a very risky practice.
When I worked at Mothers Pride bakery Wigan in the mid-'70s a Rank Hovis driver set his tank up for discharge, got it going and then went to the canteen for his breakfast, leaving the tank unattended. The product discharge pipe came off the back of the tank, and take it from me when there isn’t any resistance from the pipe flour under pressure comes out of the tank very quickly. It was also raining very hard which didn’t help, and as I ran to try and switch off the land based blower in the silo house I slipped in the gooey wall paper paste-like mess and fell into the morass. A bakery engineer with the same idea also fell into it all. It was like a slap-stick comedy routine. It was impossible to get to the back of the tank and turn off the product valve such was the amount of flour coming out. It took days to clear up the mess.

I worked at an animal feed mill and they used bulk blowers to deliver the feed, one of the drivers coupled up his pipes started to discharge the load and got back in the cab to read his paper, the pipe came off the bin and blew around 2 ton of layers mash across the farm before he realised, yes muggins here and a lad out of the mill ended up going out and bagging it all up!

Well in my time I have paid out quite a bit on Eminox exausts as has been mentioned it freed up space on the chassis and I used to have boxes made to stow gear in like toolboxes and oil cans etc, they were not a cheap item back in the day and I can remember taking motors to them for while you wait fitting think they had a place in Abington IIRC. to be honest I never had a quibble about quality and found them to be sound. The first examples I had were on a 141 as in the picture below and also had one fitted on the first new motor I bought which was a Globetrotter in 1986.
When we had our first FH Volvo’s the factory upright exausts used to lean out so you could not fit the wind deflector kit that side so we got MC truck & Bus to cut and shut the frame so we could fit the kit, once we had that done on the first four in early 94 every body else followed suit and in the end Volvo modified it before it left the factory.
Eminox and other upright exausts are ok to a point, more glitz and glamour really and if they were not high enough the exaust gases could make a hell of a mess on a tilt of worse on a white fridge box, cheers Buzzer.
By the time that I was dealing with Eminox - they wanted the vehicle for a week IIRC - reluctantly they made a kit up and I fitted it, but it never fitted very at all, and it leaked quite a bit - which in their words would “seal itself up in time” - that was on a DAF XF- not exactly a ‘rare’ vehicle either…, I guess that they didn’t like sending kits out for others to fit, as they were never easy to deal with.
Re the exhaust making a mess of trailers - I can’t remember who it was, but when I was an owner driver, one of the European fridge companies wouldn’t let anyone with upright exhausts pull their trailers, can’t remember who it was though - you’ve certainly got the exhaust up high on your Volvo there, and the front of the fridge is looking good…

ERF with a ■■■■■■■ and Jacobs brake,made a lovely sound coming down Heads of the Valley with a D9,blade and Kelly Ripper onboard,although I did have to keep the window up,unless the office called me up on the radio of course!
I had three Foden’s with vertical exhausts, not Eminox though, and they were ok. One had a flap on it, but being a ■■■■■■■ L10 it ran fast at tickover so it didn’t rattle in my lug 'ole! I read years ago that vertical exhausts came about in the thirties in the USA when vehicles were failing to see ■■■■■■■ engined trucks through the black smoke and hitting them behind, ■■■■■■■ simply shoved the exhaust up hill to solve that problem! 
After I finished driving I used to do some maintenance on a Foden with a L10 ■■■■■■■ that a Ballidon haulier ran, he usually parked it up over winter and when he came to start it the thing just wouldn’t fire. He had checked the electric fuel cutout etc and changed the filters. We put some spare batteries on it and it spun over really quickly but nothing happened, then suddenly after a few minutes a fountain of water shot from the stack and soaked both of us and the engine kicked in then! Just before he parked it up he had a new elbow fitted on the exhaust, not by me, and they hadn’t drilled a drainhole in it.

It was generally the food / pharmaceutical industry who stipulated upright exhausts as many vehicles were tipping inside the premises with milk, cream, chocolate, jam, vinegar, ketchup, glucose.

I wrote earlier that they had been going quite a while, but maybe not as Eminox, the website history suggests they started in 1978 by Emerson & Milles Inoxydable. Maybe it was a brand new company when I went on an almost daily basis, but it seemed to be up and running before that. The old place was off the A15 between Caenby Corner and Scampton as I remember.
The parcel carrier I worked for paid us a percentage of the first three months business if we got a lead that turned into a sale. I earned quite a bit of money on this from various customers. I seemed to have a knack of talking to the right people and promising the earth, so they did send stuff out to other customers, maybe only spare parts rather than full systems.
From what I remember the guys were really friendly, most of them from the farms around that part of lincolnshire.

Sure the Buffalo i drove was M reg, so '73 registration? Leyland must have been one of the first adopters of a standard upright stack.
With the turbocharged engine the vehicle was quite a flyer, the range change box used was perfect for the engine’s power delivery each change ideally spaced making rapid progress possible, as said it sounded superb too.
IIRC the Buffalo had the turbo, so it whistled on full bore, the Bison had the same engine but without the turbo, so it was more of a grunt than a whistle.
We had quite a few eminox fitted to erf,s over the years starting with a C series about 1985 tried a wasey? on a daf 95 which which was ok the only problem we had with uprights was a foden with the 350 cat which used to blow the tail pipe off no matters many clamps you put on it.Sometimes the driver picked it up and sometimes he couldn’t.

The fixed head engine Leyland Buffalo of that era had the exhaust at the back of the cab as already stated. This was the standard fitting, the option being the front mounted exhaust for fuel tankers and to comply with pet. regs.
No doubt they copied Tate & Lyle for their “enlightened” thinking (?) as they were using them well before that date.
The reason for fitting was to stop the customers complaining about exhaust discharge and standard fitting being at around ground level would, and could, go into the factory doors etc while the engine was running for the discharge.

I was going to ask if you had any photos of the Mandators with the exhaust up the back , i’ve never seen one but after reading about the pipe coming off the tanker have you any photos of that incident 
^^^^^^^
Yes I have a photo of a Turners British Sugar Mandator with the exhaust at the back of the cab. I’ll scan it and post tomorrow.
There aren’t any photos of the detached flour pipe incident, believe me, at the time the last thing on the minds of those of us rushing about was to stop and take photos. It was 1974 so no mobile phones with cameras, and not many people took a camera to work.
To free up space on the short (3.2m) wheelbase, in order to fit another fuel tank (Ford Transcontinental BTW, because it had a cut out for the spring hanger) I bought a second hand Eminox bracket and silencer etc (£100). The silencer was NOT of stainless and the shield was chromed steel.
The batteries went under the air tanks where the oval exhaust was, mounted on a slider tray.
The silencer rotted out so was replaced by a straight through pipe. Barked throughout the tunnels in Italy, especially between Vent. and Genova.
Never had any issues at MOT time. Mainly because when the tester is standing next to the stack, during the smoke test, the noise of the engine drowned out the exhaust bark. I only used to worry at brake test time, refilling the air tanks and being outside the Station Managers office!
All Eminox systems have a serial number. The place at Didcot could tell me the vehicle it was originally fitted to and when! Traceability back in the early '80s!

It was quite a simple installation, just an upright pipe taken from the silencer box in the usual place on a Mandator. Click on photo twice to enlarge)

It looks new there Graham , i suppose that’s the most “blinged up” working AEC i have ever seen .

It was just out of the paint shop, they hadn’t put the rear hub covers on or the front wheel nut rings
It appears that the air intake for the bulk blower is low down and could also ■■■■ in exhaust gases if the original exhaust were used? Another potential issue avoided by a high exhaust?
