This is Lot 35, it followed me home. I've ordered a correct reproduction holster (Cavalry draw with 3/4 flap) and some REALLY expensive .45 auto rim ammo.
From what I've been able to research this one was born in 1918. It was (one of 10,163 S&Ws) rebuilt in the Springfield Armory in Fiscal Year 1941.
Very nice find!
