It has possibly changed ownership from Canadaicon to UKicon and or others or vice versa as have many Lee Enfields over the course of their time in service. I have seen Canadian Longbranch, American Savage, Australianicon Lithgow and Indian Ishaphore Lee Enfield's finished in Suncote or Black stoving paint over the years, does that mean anything, not really, those rifles may have been passed through different ownership during the years. I know for a fact that the Australian Military used a version of Suncote post war so why would Canada not as well. It also could have started out as a Faz made rifle with a worn out receiver and when it was rebuilt they used a serviceable Maltby receiver from a scraped Maltby rifle. I know that when I spent time in the Base workshops we never just made up serial numbers as they were accountable so I find it strange that they would give a Faz serial number to a Maltby rifle, but who really knows or cares, it is just a dewalt rifle now which is only good to look at and hold.
