Re: Old 20" Springer Bike Frame
Well mapbike I had my suspicions of what you have there, and I was correct you have a Murray Wildcat made in Dayton, Oh. from the 1960's The only thing I don't know about is the springer forks. As the only springer was on the Firecat but that was a chopper of the same time frame. You could very well have a one of a kind. I think the forks are from an old schwinn though those were popular to have springers at that time. Either way It's gonna be cool when you're done. Please post some pics.
Here's a couple of the original ads for that bike. The full page ad even gives you the different tire sizes.
Hope it Helps. I am also a proud member of the 20 MPH. club
