Hi , I built a replica from scratch except the motor and rims , the rims I used were of an old 50 or 60s kids bike, I machined up the hubs and used a honda 50cc brake drum and internals , the downside of using these rims is the 12G spoke nipple was a bit big for the dimple in the rim, I tryed to find these dutch guys with no luck , there was a guy on EBay uk making repo parts at great cost and he said he was going to make rims but he never got back to me . It is good fun to ride around at air shows and re-enacting weekends here in New Zealand , If any one is interested I will put a photo up.
Regards Ian Staples
