L. Brown, Condor,
Thanks for the information - and pictures of your beautiful guns, Condor. I think I have my answer. Once I realized the chamber for my gun was only 2 1/2" inches, I thought it might be pre-war - maybe even in the 1920's, which was surprising to me but not inconceivable; however, I can tell now that 2 1/2" chambers continued to be made after the war. The US market was mostly 2 3/4", but England and Europe still made 2 1/2", and I suspect the British influence on gun making in Japan was still relevant, so 2 1/2" were proably continued there as well - at least until Browning and Winchester gained their foot holds.
So, I assume my gun is post-WWII - probably in the 1950's.
Thanks.
