My uncle bought a 1935 BSA 35-4 (I think) from them in 1937 for £20. They had wanted £28 for it but that was all he had as a 17 year old just out of an orphanage. They delivered it via train to Laindon Station in Essex free of charge. He uncrated it, put it together (a bit) and pushed it to my grandparents home about 2 miles away.
Picture is of me trying it out for size - think I was about 4 or 5. I used to ride on the tank on a folded inner-tube.
