I assume the rifle is from Afghanistan.
The Afghans made Martinis at the Royal Ordnance Factory in Mejar, in 577-450 and 303 Brit.
The Afghan rifles were supposedly made from scratch as well as utilising british receivers.
If it's a 577-450, it will be quite obvious by looking at the muzzle.
Interestingly enough, the 303 Brit rifles have the same bayonet lug as the No1 MkI rifles and utilise the same bayo. Every part on an Afghan built rifle will have the last two digits of the serial number stamped on it. The finish and fit will be quite professional as well, almost as good as any British made rifle.
The Khyber rifles I've seen are a whole different ball game. They are very close but crude in most cases. There's always the exception though.
Usually, Khyber rifles will have only English letters on them in the case of the Martinis or Enfields. The nomenclature is often mispelled and sometimes the letters/numbers/crown are upside down or mispelled. I've never seen any Cyrilic letters on any Martini or Enfield. That doesn't mean they don't exist though.
The Afghan built rifles I've seen, are professionally made on high tech equipment for the time period. They are made out of as good of steel as any British Martini and quite accurate as well, when they have decent bores.
From what I gather, there are usually several available in the shops. Bayonets are quite rare though. Pick a rifle that has a shiny bore and see if you can also find a proper bayonet for the rifle.
Those rifles are quite highly sought after by collectors, if they are in good or better condition. i don't mean for their age either.
I recently sold one for $700 to a chap that just had to have an Afghan Royal Armory bring back Martini. It was in at least VG condition and had a bayonet with it but no scabbard.
