The serial number on this 20-gauge Lifter is 10165 and the pin separation is 18MM which translates to less than 13/16" which is the 0000-frame size. In fact, it is more than 1/16" smaller - which would make it slightly smaller than a 00000-frame size...
if Parker had
ever even made such a frame size. The frame sizes were determined by firing pin separation at the breech face and are incremental by sixteenths of an inch. The 0-frame has a pin separation of 1" exactly. The 00-frame has a separation of 15/16" exactly... and so on.
My point is that Parker Bros. could have easily made a .410, even in a lifter, if they so desired. That bore size was certainly being made in the British Isles at that time.
