I would guess that Martyn's harpoon gun is a later production, purpose built unit, rather than the earlier production adaptions from std. issue rifles.

Indeed, it is the 'Bomb thrower no 3' and it used a falling block action a la Martini Henri. these were the more common type in NW Europe and were often seen on early Shermans.

I have a pair on mine.
