So I think. 2.5" barrel, no markings whatsoever on the gun. POSSIBLY someone has sanded/ground the finish and all markings off. ALSO the left side has open areas where you can see the innards, it does not appear that there is a plate missing or anything. As a matter of fact the plate itself is what has the holes. Is it possible this was a sales demo model? Seems fairly tight to me. Walnut grips so 1923-1947 according to what I've found. Barrel appears to retain its bluing but frame is a brushed raw finish. Neither blued nor shiny nickle. Cylinder is the same finish. What do you guys think? Apparently a preferred carry gun by many according to the interwebz
