According to stamp on toe of grip frame, was refinished at factory 4.48. Matching serial numbers, stocks not numbered. "O" stamped on left side heel of grip frame, on barrel flat, and on rear of cylinder behind the extractor star. Have requested letter and will post all information and pictures (to the best of my limited ability) when received. No ordnance marks, no "Made in U.S. A." Serial on barrel flat preceded by a "B" and followed by the "O".
Thanks, I just can't figure out the year and would dearly love to know when it was shipped. Appreciate the help.
