Been after one of these for a while and was lucky enough to find this on my latest haul.
Its made by W D Stubbs of Nottingham who are still in business making carts and trailers, it measures 5 foot x 2' 6" and has lift out sides, ive spent a bit of time on it today and got the wheels to go round and the turn table to work, it needs 4 tyres and tubes, it has 1" axles so a bit restricted on swapping wheels.
The wheels are 8" and the tyres are marked 14x3 , ive got a few 400x8 but all different tread patterns.
Anyway heres some photos
