The work he did on the BREN is just as ingenious using M1 carbine hammer, FAL hammer spring in the innards to get it firing from a closed bolt. His weld up of the receiver was purposely made more visible to assure BATF that it was made from a destroyed receiver. Externally it is an exact copy of a Mk1 BREN.

Over the course of several years pending my finding destroyed receivers, he built semi auto FALs, Indian, Canadian, Australianicon and several Britishicon. Of course we can't do that stuff now as the current rules for receiver destruction cut swarths so big that simple welding can't bring them back. When we were doing this all that had to be done was to cut the receiver into three parts. He also did a wonder TRW M14icon with dummy full auto parts for me. We were playing with a semi Lewis gun when my parts sources in Canadaicon dried up. Oh well.
