Belarus,Ukraine,Bulgaria?I can tell you that in the sixties many old bike shops closed,and the stuff was taken to the tip,because the scrappies wouldnt take bike stuff,not enough weight.When I was a kid ,a man in the street made aluminium pullies for electric motors etc,using ally from bike crankcases.I got tons of Indian and Harley iron from him free,a complete1947 SV74 Harley,less cases and box,heaps of WLA and army Indian chief stuff.The price rose quickly in the early seventies,and I did allright.Back then you couldnt give away a M20 or 16H,side valve slugs.Regards John.
