Here is an interesting replica firearm I just acquired by chance.. know very little about it and would encourage any opinions or info in general! It is marked Hudson and I believe that is a Japanese firm that produced these. It is of steel and plastic construction and quite heavy. The magazine operates as the real gun and wire stock slides and locks in place. Any pointers on how these work would be great!! I would like to move this along to a reenactor or collector who appreciates these so any idea on value is also appreciated. Best, Kevin.
