I got this with some other items recently but have only just got round to looking at it . I had assumed it was an L2A2 body but it's not . The internal copper fuze holder is wider at 0.57" & the L2 igniters are to small to fit . I was wondering wether it was the US M26A1 that took the M217 igniter that , I think , had wider threads than the standard M26 ? This body came with a sectioned example containing the frag coil & probably came from a British source but I think the British trialled the M26's in the 1960's ? Any thoughts would be appreciated .
