Cranks are steel like would have come on an 40-50's Paramount. It was apparently on ebay before( Dec) cause he said in add, was relisting it due to the fact top tube got dented dissembling it .hoe do I get a hold of Bob Freeman? I think it was back and repainted between 63-68 has decals and pin striping for this era seat mast decal has Arnold Schwinn on it.. $400 shipped I'm ok. Last set of cranks and bb like these on ebay went for $175. I think he would have parted it if he would have done more research. I was happy he took my offer.
