Looks like a mod. 1905. But I haven't seen one with these grips before. Small rounded hard rubber "black", diamond around the screw, S&W logo at the top. Ser. # 129746 is on the butt, bottom of the barrel, and on the cyl. with 1541 inside the yoke where mod. # should be. The right side of barrel say's, Smith & Wesson Springfield, Mass. U.S. Pat's. March 2?. 94. May. 01.95. Aug. 4.96 Dec. 22. 96. Oct. 8. 01. Dec. 1?. 01. Feb. 8. 0? On the left side says. 38. S.&W. SPECIAL CTG Four screws on the right side and the "S&W Trade Mark", one screw in front of trigger guard and one on front side of butt. It's old and in poor cond. but my wife likes it because of the small grips. Action is good, smooth and tight. Light load wad cutters makt it fun. Does anyone know the Mod. and year it was made? Thanx, Steve I was trying to include a photo but haven't been able to, I don't have a URL.
