Dutch army, Johan Herman Fuhler, somewhere between 1945 and 1950
Aren't those the ones that Norton deleted because they trapped water and caused premature bearing failure?
So owners of bikes that came with them would have removed them and thrown them away.
Hopefully David they would have put them in the shed at the bottom of the garden instead of throwing them away. Then they will turn up 84 years later and i can fit them to my oily rag 16H.:relaxed: You never know.
