The Mazar i Sharif mosque stamp, is also found on firearms made & permantly stored at Kabul.
The same mark appears on Afghan Coins,stamps & flags.
So personaly I see it as rather more a Royal Afghan Symbol of ownership rather than a dedication of where it was made.
Ive had 6 such marked pieces, one was probably a German made {certanly European}double fullered trade bladed sword , others were tulwar type swords,bayonets & a kukri.
The Afghans adopted & copied many weapons, as I expect they still do.
