Post war, I believe only Faz and POF in Pakistan built mk2 rifles.
The Pakistani built POF rifles are easily distinguishable from the British FAZ built rifles.
All of the Pakistani rifles had very dark, straight grain Circassian Walnut stocks, supposedly they all had reinforcing pins, but I don't know.
When they were first brought into Canada, I bought ten that were unissued from International. All of them had almost invisible 5mm square, inserts glued over where the reinforcing pins would be on the fore stock. I never took one of the inserts off to find out.
However, I did see a couple that were ridden hard and put away wet and where the inserts had worn down until the brass pins were visible.
Another thing with the POF rifles are their major bore diameters. All of the rifles I had measured out to .310 diameter.
Likely used the same drills and rifflers or if hammer forged, buttons, which they used for the AK style weapons they produced at the same time?
The POF rifles were better finishished than the FAZ rifles and not nearly as ammo fussy. IMHO of course.
