First time question from me, I'm pretty curious about a old gun I got from my mother-in-law for Christmas. Model 1894 S/N 154,xxx, 25-35 W.C.F.. Looks to be in "Fair" condition according to what I've read so far about grading. Preliminary search looks like a build date about 1899. My question is if that is accurate and if there are many of these still around.
