Just got a phone call from a gentleman who was told by my gun shop buddy and owner that I may be interested in his like new (74 or 75?) Marlin 39M that he has for sale. He tells me that it is pristine, not even hardly wear marks from the lever being worked?Wood is pristine as well. Anyway, he is asking $600.00 for it. I do not have $600.00 right now, but I am "toying" with the idea of offering him my like new w/box Ruger 77/17 in trade. What do you all think? Good trade or bad trade?
