A few years ago I purchased this gun in Fort Worth, and know in a general manner what I have, but would like some more specific information if possible. It is a Smith and Wesson Hand Ejector, Serial Number 27XXX. The serial number is on the bottom of the butt of the grip. The barrel is marked "38 S & W Special" and underneath that is "U.S. SERVICE OTG'S"

The top of the barrel (as best I can read it) is marked:

SMITH & WESSON SPRINGFIELD MASS U.S.A.
PAT'D APRIL ? MARCH ? 04 MAY 21 ? JULY 16 93
AUG 4 96 DEC 22 96 OCT 4 98 ? ? DEC 17 01

Thank you for any information you can provide me with about this piece.
