My dad inherited a pistol when his brother passed away several years ago, and only recently pulled it out to see what it is. Took it in to a gun shop & was told it was an old .44 special. Just recently brought it down and showed it to a collector who told him it might be older than he thought, but was unable to give any specifics. I read the thread here on how to help identify, so here are the specs:
It is a top-break revolver, SN 33406. Appears to be .44, but there are no barrel markings or any other markings that can confirm caliber. Barrel length is 5". There is a strain screw, no butt swivel, appears to be a three screw (no trigger screw).
More information that you may or may not find pertinent:
Top of barrel is marked with patent numbers. Exact phrasing - top line = "SMITH & WESSON SPRINGFIELD MASS. U.S.A PAT'D JAN. 17 & 24 . 65"
Second line = "JULY 11 65 AUG 24 69 JULY 25 71 DEC 2 79 MAY 11 & 25 1880"
I took several pics, but haven't checked yet to see what the restrictions are on posting them. Will read up on that & get back in a bit.
I appreciate any help anyone can give.
