Well perhaps that is the problem I'm having then, I don't have a wrench that will fit in between the crank arm and the pedal to grab onto the shoulder and turn it. Every wrench I have is too wide. Any suggestions on where I can find one the right size? Also, I knew about the factory fire and the lost serial numbers, I just thought maybe someone would have an idea maybe. I pretty much know it's either a '38 or '39 Hollywood. It's already been sold, so I was just curious really. Thanks for the help everyone! I really appreciate it!
