Clockwise from upper right:
Colt Police Positive, 1921, 38 Spl, 5" bbl, Nickel, Colt MOP medallion grips, unknown engraver.
Colt Detective Special, 1928, 38 Spl, 2" bbl, Nickel, MOP grips, unknown engraver.
Smith & Wesson Mdl 60, (Stainless Steel Chiefs Special), late 70's, 38 Spl, 2" bbl, Ivory grips, engraved by Ray Viramontez.
Smith & Wesson Mdl 36-1 (Chiefs Special with Adj sights & 3" bbl), 1967, 38 Spl, French Gray finish, Ivory grips, engraved by M. Woodson. Unverified story on this one is that the previous owner killed a Cougar with it and had it engraved to commemorate the occasion.
If anyone can give me any information on an engraver named M. Woodson, I would appreciate it.
