As you can read from this thread so far Fred; Fazakerley had enough troubles on their plate, of their own making! And while the rest of the UKicon Arms makers were gearing up to produce the L1A1, Fazakerley were struggling on, still producing No4's that nobody wanted. The last big UK order for the UF55 series were for the RAF/Navy who feared that because of the slow down in L1 production, they wouldn't get them.

Great info Mk7 that seems to fit in with the little bit I knew
