Re: Hello from the San Fernando Valley
Welcome to the forum. I pant pant pant for panthers! Great frame, well made and good looking, too. Look on ebay. I have a 1950 with a four stroke and sidecar. Panther was just one model that used the same straight bar frame. We tend to call all of them Panthers,it being a sexy name and all, but as soon as you say "panther" the price goes up. So, look for Schwinn frame or narrow it to 'vintage'. You might also want to just look around at vintage bicycle frames and you may find something very similar to the Schwinn straight bar that you like. There were lots of them back when. Good luck and share your build as you go. We like pictures! Judging by your name here, you know your way around small engines. That's good.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
