Les Sylphides:
Well chaps, the replies have certainly surprised me! Thank you. The winding motor may well have been electrical with manual over-ride. Early '30s cars had a little T-piece knob you could turn to move the blades.
Didn’t the early Landrovers have that kind of set up.

Now that rings a bell! I drove a 1949 Landy once and I’m sure that had 'em
Land Rovers had them up to the early 60s, each side of the screen had a separate motor and if you pulled a little lever back you could operate it manually. You also had to lean over to switch the passenger wiper on as they operated independently. Made your wrists ache after 10 minutes in heavy snow.
It’s always nice to stumble upon an old picture of a lorry you once drove! This is a nice action shot of Border Olympia on a wet motorway. I briefly drove it in the ‘80s. It had a Roller 265 with a 9sp Fuller in it – a satisfying combination BTW.
[Unabashed fancier of Middle-East spec ERF NGCs with spready TIR-tilts!]
EDIT to add: in the unlikely event that the photographer comes on TN and still has the dates for when he took his pictures, I could - given the date - tell you if that’s me at the wheel or not!
