Hi guys picked this up today, can you please identify the frame? Pretty sure its steel but got unusual shape on the rear stays, also the joint behind the seat tube almost looks like suspension, the rear stay is bolted in and not one piece.the guy was pretty sure it was a Raleigh and a high spec frame in its day.thanks guys I look forward to some help thanks jon
