Yep, Charnwood seemed to employ engineers for the task, while others employed blacksmiths... (I also have an ex NZ Charnwood example in superb order) Good luck finding a Britishissue Faz made L2A3, Peter has gone into the reasons for their (almost) total absence from the collectors market before in some detail, basically, Government skulduggery again, caught with their trousers down manufacturing L2's at ROF Fazakerley without having the manners to inform, ask or pay royalties to The Sterling Armament Company !
A deal was reached, where Sterling would provide all export examples and spare parts and Fazakerley would solely manufacture examples for the UK, a caveat was also included detailing the scrapping of surplus Faz examples, prohibiting them from onward sale. (Is that about it Peter)??
That said, one of our merry band has a Faz example in his collection, so some got through .. I would guess, lost in pooled ordnance at some point, so escaped the axe! Got to be a rare example now..
