If your pump 12 ga. has an exposed hammer, it's most likely a model 1898, as all later models of exposed hammer Marlin shotguns had the model marked on the upper tang behind the trigger. If it is not an exposed hammer, then the model designation is on the bottom, where the receiver meets the mag tube.
Model 49, 3000 made form 1925 to 1928 only
Marlin Model 49 Exposed Hammer Pump Shotgun, 3000 made 1925-1928 for stock purchasers only, 12 gauge 2 3/4" with 30" barrel, 4 round magazine
The Model 49 was a variant of the basic Marlin pump shotgun produced on the 1889 patents. The Model 49 was made in the late 1920's and was primarily an incentive gift for stock purchasers. Due to several different potential problems with the action, Marlin advised owners of these guns not to shoot them.
This may- I mean MAY be your rifle. It's a model Marlin Model 49 slide action Shotgun. Exposed hammer takedown combined features of the model 42 and 24. It was never in the Marlin Catalogue. It was made between 1925 - 1928.
The Marlin model 26 shotgun was made from 1909-1915.
Hell yes its worth fixing i have a 20 ga . Marlin model 44 and i would not take 500.00 dollars for it.The Marlin model 44 in 20 gauge only was made from 1923-1935.It should be noted that in 1998 Marlin made a statement that all exposed hammer models along with the hammer less models(which you have) should not be fired due to there age and that system failures can and will occur.While a repair to your shotgun is possible,just be advised that these shotguns will probably only handle low brass shells due to age,and condition.
