39D 39D owner here. I bought it used at the big (semi) local sporting goods store back in around '72 or early '73. It, along with my Stevens bolt-action I got for my 16th or 17th birthday are the oldest guns I have. I love my Marlin. It's going to go to my daughter when I die (as my son's wife is vehemently anti). FWIW, I'm taking my wife shooting tomorrow for the first time (third wife... don't ask) and I'm planning on using the 39D to break her in right. As opposed to the AK in 7.62x39.
