I originate from Rotherham & remember seeing them load in the steelworks of Rotherham & Sheffield. They then went and had another 20 tons loaded on top in their depot for their run up to Scotland. They had one of their trucks used in a Motor Transport road test & it broke all the records for speed & economy + ripped off the trailer headboard when they did the emergency brake test. Obviously a 5 axle rig in those days was going to stop better than the load - as one of the members noticed, steel held on by ropes.
It’s hard to believe that they delivered so little power or that you needed to take both hands off the steering wheel & double de-clutch to change gears with their twin gear sticks but I know that’s what was needed.
jonb2610 But they had airbrakes while we were running round with those stupid vacuum brakes. Steel loads were steel banded right round the trailer at the steel plant in those days. But of course not around the front.The ropes were to hold the sheets down
Harry Where I had worked weekends & holidays as a kid & then passing my C & G motor vehicle mechanics exam all the 4 wheelers had vacuum brakes but the artics had air. We always chained our steel loads on & the only ones that were banded round the chassis were the ones going on export with drop trailers like Ferrymasters, Trailer Express/Bilspedition etc. I remember being taught to drive on the understanding that your brakes were for parking & as a result even my car brakes last about 120,000 miles on the original brake pads & I don’t drive slow.
Yes , I seem to remember that the AECs had air brakes . But I was in the slow lane with clapped out BRS Leyland artic. In those days steel was banded to the trucks no matter where it was going. That from the steel works. Queensferry, Port Talbot, Newport, ect. But I do recall using dog & chains as well.

Welcome to TN Mick, let me be the first to demand some pictures as your
brother’s work progresses. I didn’t know that P&S were still in operation when
the R series came out. I certainly never saw one. I worked in an (almost) all B
series fleet in Oz in the late 60s and the boss drove an R motor, the first most
of us had seen
Hi Alex I remember NET of Montrose with their “Whites” as they had a depot at “Coburg Dock” in Liverpool as they used to work for what was then “BOCM” (British Oil & Cake MIlls) as they had a dock shed on Coburg Dock to store the grain etc. that came down from Montrose as they also used to bring down the (I think) “Brewers Grains” from the whisky distilleries as did “Strachan,s of Turriff” with their F88,s with the (then) “walking floor” which was ok till you got to
the last few tonnes of grains and then the driver had to (literally) shovel the load on to the belt below the floor which came out of a schute at the back then he had to put back all the floorboards to cover the centre of the trailer before he could re-load 
I am posting a couple of pics of the p&s macks that dad used to drive parked at kellys cafe at boroughbridge. I have shipped a B model from U S & am restoring in p&s colours, does anyone have a side veiw to see the livery on the door ,
Hopefully this should help:
Hey, are you on the run from someone MickM/Paws? 
Thanks for the pics though, you learn something new everyday. Still think the B
motors were the tops for design though, always a sucker for the more
rounded bodies, me. 
There’s a couple of pictures available on e bay of these two right now
this ex p&s R model as seen at dorset steam fair now from ireland…

Found these on me travels in Canada last year;
This one was awaiting restoration outside…
And this was how it looked in its working heyday…
Just happened to come across these “beauties” in the old photo shoe box…
Hope they are of interest, especially to you Paws.
I didnt take the photos. Nice yard: right behind the houses! Would have loved to live there.
Paws: you have a PM

As I said to Paws, you learn something new every day - that’s the first left ■■■■■■ of P&S that I’ve seen. Were there others?
The other thing that occurs to me is the lack of sleepers. Did those blokes never stop, or did they go in digs? True all the B motors I’ve known had a passenger bench seat, so flat right across for sleeping, but hardly a wide enough cab to stretch out in. A bit like that Scammell Constructor I had to sleep in in Econofreight’s yard when my Daf was in for service - and that was in the bunk. 
Think they only had two left hookers out of the fifteen…As for sleeping,
dont think they had the time !! 
Great pics truckerash…
