This old gun.

[tbonin1]

I have an old Remington shotgun, I think it's a model 11.
Serial #253153
On top of the barrel : Remington Arms Union Metallic CTG Co. Inc. Remington WKS Illion N.Y USA. Patent 10-9-1900, 12-17-1901, 9-30-1902, 6-16-1903

Would like to know when it was manufactured. I am 58 years old and this gun belonged to my
Grandfather. Born in 1882

A picture would help and placing this message in the post 1899 shotgun section will get more response to your question. I am not an expert on Rem shotguns but a model 11 Rem is very distinctive. It has a receiver that is squared of at the back the so-called "humpback" and it looks exactly like a Browning A5. It is the Remington liscensed version of the Browning Shot gun. If you go to the home page and follow the manufacturing dates link there is a link on the barrel codes page the allows you to down load the serial number records where you can look up model 11s by gauge and year of shipment.
