I believe the Marlin you're speaking of is the Marlin 410 Lever Action. I have a dandy of one my Dad bought in the early 1960's. They are great guns!!
No this was a 22 pump I believe.
Well, we are both right! I just flipped through Brophy's book on Marlins and both the Lever action 410 and the Model 47 22 pump "along with some others" were offered for free with a purchase of 4 shares of Marlin Stock. Enjoy your day, Ed
