VINTAGE 50's AMF SHELBY AIR FLO UN-RESTORED, USA MADE, ALL ORIGINAL! in Clearwater, Florida For Sale

This bicycle was found in our grandpa's barn in Ohio, it will clean up to look great. I "test" cleaned it in a few small spots to see if the "film" that shows up in the pictures will come off, it does to reveal almost perfect chrome. Not sure if "I" should clean it at all???? Looking for offers from someone who knows old bikes, I found just the seat PAN all rusted on ebay for $89.00?????..................Josh
P.S. I also have this listed under "antiques" with a few more pictures.
