Very nice assembly and I appreciate you going thru the effort to display them for us.

I have two, a 95% circa 1952 I acquired a few months back, and a 98+% circa 1949 that I have had for 10 years or more. My 1949 (according to the 3rd edition) has the heavy non-tapered barrel. I assume from that, it was in that year they changed to the heavy barrel. Mine is serial #810xx. Thanks again for explaining the differences in each model.
