Sten MK5 identification help please.

[Lee Enfield]

P.O.F. is Pakistan Ordinance Factory.

Unlike the Indians, the Pakistanis don't seem to have "wiped" the original manufacturers markings of their weapons.

it's probably an FTR of a British manufactured STEN, but it's possible that POF manufactured STEN Mk5s into the 1960s.

Are there any other manufacturers markings?
