It's not a 1905 that's just a patent date, they actually didn't make them that early could find year by serial.
BUT - just like a car is it in the showroom or the junkyard, value is determined by condition, condition, condition, and condition.
The Remington Repeating Shotgun was introduced in 1907. The name was changed to the Model 10 in 1911. In excellent condition, it has a blue book value around $300.
Most likely, the pump shotgun you have is a model 10. Uncheckered wood, grooved slide, value is from 150 to 300 dollars.
Remington never made a Model 1905 22 rifle.
Remington didn't make a pump shotgun until 1908 and that's a model 10.
Odd question... It's a auto-loading shotgun made from 1905-1947, actually it is the FIRST auto-loading shotgun produced in the U.S.A. !
The value of a 1905 model D single barrel choke bored Diamond Arms shotgun is actually dependent upon a number of things. Most importantly the condition of the shotgun.
Sounds like a model 11, 1905-1947.
Model 1905 WHAT? What make? Rifle, pistol, or shotgun?
Pretty much almost impossible to tell the model just by the sn.
I think your referring to a model 11, made from 1905-1947.
I just so happen to own a Remington UMC model 10, actually it is pre model 10, they did not name this the model 10 until 1911 I believe. Mine actually has the dates 1903 and 1905 on it. But to get to your answer it stands for UNION METALLIC CARTRIDGE.
1905 til' 1949
