get ready to have your preconceived notions thrown out.
Firestone began offering bikes in 1936. Firestone didn't actually build these bikes but contracted with someone else to build them. the most common of thes makers from this era are Huffman and Colson, but there are several Cleveland Welding made Firestone Fleetwoods out there in decent original condition. a little searching of this site will find them. your bike has the wrong wheels on it. it is indeed a Firestone Fleetwood made around 1936-37 and was originally a 26" bike. it was also made by the Cleveland Welding Company for Firestone. these are semi rare and interesting bikes, though not terribly valuable.
this is not your bike, but the catalog page from the 1936 Firestone catalog. this is a Huffman bike, but yours was outfitted in similar fashion.
