Both Winchester and Marlin made "trade name" guns for others. National Fire Arms appears under both names in my references, including one very much like the Winchester 1897.
Winchester model 1897 12 gaugeThe 1897 Winchester model 12 gauge pump was manufactured 1897-1957. The standard barrel length could be ordered from 20"-36". The value depends on condition,The year it was manufactured, and also historic value. If it have any markings such as police use, military use, or any other historic use the value would be much higher, for example the U.S. Winchester Model 1897 slide action trench gun $2,800-and up. Without examining your shotgun, if it is in decent condition, working order, no special historic value it should sell for between $500-$700
.410
it stands for Winchester Magnum Rifle.....it takes a 22 MAG BULLET
Any 12 gauge shell made with a length of 2 3/4in.I would not use steel shot shells in your model 37 though.You can also use brenneke slugs in your shotgun also.
They are made in several different calibers. Look on the barrel to read caliber markings.
A trench gun was a shotgun used in WW1 by allied forces, a Winchester Model 1897 to be specific. It was so effective in its' military use Germany attempted to have it banned from warfare for causing unnecessary suffering.
A "bullet" is the term used for a rifle cartridge projectile. The Winchester Model 37 is a shotgun versus a rifle, and as such, it primarily was made to use shot shells (hundreds of small lead pellets) used for hunting game birds and waterfowl. Bert H.
If you need to ask this you shouldn't own let alone be shooting a rifle!
The Winchester Model 12 was one of the best pump shotguns ever invented, but I'm afraid trying to chamber a round 1/4 inch longer than the gun was designed to fire would be very difficult and the pressures generated would be higher than the 9/16 was designed to handle.
May not be a wise move. Model 1897 Trench Guns are very collectable, and honest wear from use is far more valuable than a restored piece. Best have a knowledgeable collector evaluate the gun AS IT IS, first. sales@countrygunsmith.net
