I thought the Zephyr, and for sure the Dayton, decals looked suspect. A true Dayton level bike would have a Monark paisley chain ring. This bike is a Firestone "Airflex". As such it should have a different seat. The stem is a post war stem and it should have a Torrington "R" drop forged stem. I'm going to bet this has a "FBH" serial indicating a Firestone bike. Pictured below is Nick's slightly rougher identical twin of this bike with correct seat and stem. Everything on this bike is easily correctable and it is a very nice bike. GLWTS. V/r Shawn
