Hello: This is my first post. Long an admired of SW handguns. Today I went gun trading actually looking for a Ruger in 45lc. I ended up with what I think is a 2nd model SW hand ejector marked 45 colt on the barrel. I was shooting it and a man looked at it and told me it was one of the most rare calibers for this model and only a handful were around and to stop shooting it and ask a collector if it is so. The revolver is serial number is in the 30,000 range , the lanyard ring is gone, the gun is tight and locks up like a vault door, no blue and the grips are fairly nice the little checkered ones with the sw medallions. The thing must have been to Britain, it has various British marks on it. Looks like a little set of airforce wings too ! It is for sure factory marked 45 COLT on the right side of the barrel and I had some light loads that I was using in my Colt Sa and they shot great from it. I this revolver more valuable than the 400.00 I gave for it, enough to worry about shooting it hurting value. No finish left to rub off really, but a really honest looking old gun. Thanks for any help or advice. Johnny
