Definately looks like the nickel slide is there to me. Good luck hammering out a deal if you decide to go for it. It' just one of those things price-wise that there's not that many around that are available, but there is also limited demand. I would say start low or let him sit on it a while, but all it takes is that one other guy to grab it. So, I really can't offer much advice in the way of price unfortunately. It is old, that's for sure, so if it's close to you and you've been looking for one of that era, it's your deal to make
There won't be much there you can't fix mechanically if that helps you out. Thanks for sharing the pics anyway. It's always neat to see the real old ones. Amazing whats still sitting in peoples basements.
