Found a brand new 1894c at a local pawn shop. Not sure if it's a Marlin or a "Remington made Marlin". I have read that it will have REP stamped on the right side of the barrel if its Remington made. I don't see REP, but it does have "JM" at the rear of the barrel right in front of the action. They want $649.00 for it. Wondering if it's a true Marlin or Remington? Any suggestions?
