Marlin Model 39-A DL. These were made from 1960 through 1963. There were 3,306 of them made. The number by years is as follows:
1960 there were just 4 made
1961, there were 1,812 plus 125 shipped with a 4 power scope attached.
1962, there were 739 with another 88 shipped with attached scope
1963, there were 351 with another 187 made with the scope.
I love mine so much my model 881 with a scope stays lonely. I have a Lyman peep on it and bust doves with it. I got 4 European doves yesterday and had them with eggs this morning. yummy
I like mine so much I may start collecting them. Mine stays in my Ranger now.
