I assume it is hammerless? If it is, then it was made in 1910. If it is a hammer gun, then it was made in 1913. The latest issue of the Double Gun Journal has an article about these guns.

If you take the barrels off, you should see more markings. Let me know what they are. The guns left the factory Full & Full for the most part.

Prices on these guns run from a couple of hundred to well over $1,000 depending on model and condition. There are a few 20ga out there that never seem to surface. Also some special order guns.
