I just read that 113 could stand for Jan. 1913 and the larger G proof without a crown stands for black powder. Is that a correct understanding to the wise? If that is true any idea what this would range in price? The gun is in the 90 percent range, case hardening is great shape and bores are shinning and rifling is good. Just a tiny bit of movement in the in the action when locked. Wood I’d good also.
