Ours was a .22/.410 with the folding stock that also shot the round ball .44-40GG cartridge made especially for it. I have a few of those cartridges in my "stuff" here. We had the leather holster with our Gamegetter also. The gun went to a family member in Canada sometime in the mid 60's, never to return. Can't imagine the Canuck govt looks fondly on such a gun. I sure would like to have it as my airplane gun. Am thanking Edgar here for the info that they had been removed from the BATF list of evil guns. I had not heard that and am glad it happened as it seemed beyond absurd. As usual, Edgar proves himself the inveterate purveyor of invaluable minutiae.
