Forgot about the folding miya works bike. Ten minutes before finding it I bought a bike on Craig's list for $10 then passed a antique store while leaving, stopped in and was able to trade the bike for foldable. The Ross muscle bike was also $10 at a rummage sale. The other 3 were found in the weeds at the scrap yard and I got them for free. Not sure if the split backbone is a rollfast but it looks identical to my wife's only a 24". Can't find anything about the 20" Amc, very cool though.
