It's a typical Britishicon issue No.2Mk.1* pistol. Since it's an early 0T, it was upgraded to Mk.1* later in British service so the markings were added later as well as the Enfield manufacture Mk.2 hammer. Early 0T pistols that saw the upgrades in Canadaicon during factory production were stamped with a "1" in front of the "0" making them 10T. It's been back to British workshops and probably just hasn't seen full blown FTR at a big base workshop or the RSAF so the FTR markings aren't present. I've had a bunch just like it and it's right as rain.

Just an observation: It sports the Navy Arms import mark above the left grip panel. NA Co. imported hundreds of them in the mid 1990's directly from the British Disposals unit at Donnington.
