I have a Model 41 pistol which has a 7 3/8" barrel with muzzle break. It is U.S. Marked behind trigger guard. I have a letter from S&W that is was sold in 1969 (Viet Nam Era) to U.S. Army. Can someone help with rarity and usage by the U.S. Army? Training or Competition Usage? It is about 98% all blued finish with wooden grips. I have not been able to find another that has sold in the past 10 years on internet...but sure there will be collectors on the forum that have purchased similar...Appreciate email: [email protected] Thanks Hemi
