Considering what you just describe, what are your thoughts? I am curious to know if there is one particular manufacturer in Japan that was likely to produce a gun of this grade prior to WWII...and approximately what year considering that it has 23/4" chambers with relatively tight forcing cones (which were designed for shot shells with fiber wads...; The condition is quite good with still crisp checkering, strong blueing (definitely not restored in any way) all original finish. The barrels are dense with more than appropriate thickness but yet relatively light. It balances just about the hinge pin with slight weight forward (I love that as it provides better swing) but have have primarily used light 21/2" fiber wad loads -Gamebore, RST and H&H...
Thanks for posting additional pictures of your guns - there are some similarities with the engraving to the shotgun at the bottom, which one is that?
