Definitely a .38 LC New Army and Navy as noted above. The "grips" on civilian models were hard rubber and military ones almost always smooth walnut, with the exception of late production versions for the USMC with checkered walnut panels. Based on the SN and lack of U.S. military rollmarks it is either a model 1894 or 1895, produced in 1905 per Robert Best's book.

If you are buying it for display and occasional shooting it should work fine. The charge holes are bored straight through so it will take .38 Specials (and unfortunately for some in the past, also .357 Magnums). However, a "little" play with the action closed and the trigger fully to the rear is a sign of more to come, and it is difficult to find anyone to work on these.

Good luck in your decision.
