This FN 1905 is in pretty decent condition for its age, with only slight pitting in its chrome finish, and no rust.  We are not sure exactly of the age, but it is likely between 1920-1940.  After a thorough breakdown, we've determined that all parts are in great condition, the only exception being the firing pin, which will need replacement, and the barrel, which looks like it has gone through its rifling, but will still operate fine.  If you have any questions about this particular firearm, dont hesitate to reach out.
