This has me buffaloed and I sure hope someone will help. With the cylinder closed the ejector rod does not match up with the lug under the barrel straight on when it is closed. (1/16th short of matching) I have spun the cylinder and am not able to observe any wobble of the ejector rod. Looking down the top strap at junction with the barrel, I may be able to see a very slight indication of the barrel being overtightened but am not sure from naked eye inspection. (Could be imagination) Of course, this barrel is pinned and I am not aware if the hole for the pin is pre-drilled before installation or drilled after barrel is installed. This is a 1953 era gun, don't think Smith will even give it a look. Anyone suggest a way to confirm the actual reason for this match-up problem? Appreciate all suggestions and/or reasons.
