I'm a newbie and I am looking for a Panther straight bar frame and came across this one for $50. The serial number dates it back to 1950 but not sure what the model was. Do all the models that have a straight bar frame from 1950's use the same frame? Looks like a good find but just wondering if parts I pick up for a 1950's Panther would fit on this frame if is was not originally a Panther. Any guidance would be appreciated. Thanks
