Would anyone have information about a "Field. London." gun?
SLE
12 bore
30"
2 5/8" chambers
Cyl/Full
Damascus
Nitro proof to 1 1/8 oz

Only text on the top tin says "Field. London.". Serial number looks to be 378 and is stamped on the bottom rib, immediately forward of the forend hook.

Got it today from a very nice fellow, and it should make for a great project. Thanks!
