I just bought a Marlin 39 (not a 39A). I'm trying to determine when it was manufactured. It's serial number is HS 175XX and also has the "star" mark on the upper tang. I know the 39's were made from 1922 thru 1938 and that the HS prefix started in 1932. Anyone able to pin it diwn to a certain year? I should have it in hand this week. Thanks in advance!
