Where do you live? If you are still in Manitoba you could find them in Winnipeg. I see them at garage sales all the time. The Winnipeg Police Auction in April will have a lot of them. You will pay maybe $50 for one at the auction and $5 at a garage sale. I was at a bike shop close out auction last spring and bought a brand new 1980 Sekine with mountain bike style tires and rims laced to Sturmey Archer 3 speed drum brake hubs. The bike didn't have any air in the tires and the tubes looked like they never had air in them. I also bought an identical bike in very used and rusty condition. Send me a private message and I will send some info on Sekine bikes I find.
