Been doing some early Christmas shopping for my son and picked up a marlin 60 1983 vintage 22" full length tube. I wanted a piece that he will hang on to and pass down himself, as this will be his first gun from dad. By the time I have it I will have 155.00 in it, overall it looks to be in pretty nice shape. The stock has some scuffs/scratches in it. Trying to decide if I should refinish the stock or give it to him as is. I always like to leave things original as possible. What kind of collectability will the vintage true marlins have in the future?
