From the date, it must be Egyptian or fake. And it is a Martini-Enfield, not a Martini-Henry. I.e. Martini action with Enfield rifling, not Henry rifling, which was only used for the 450 caliber.
The .303 Martinis that I have seen over here have almost all been carbines. Egyptian "Citadel" production, for (I believe) the Egyptian police, i.e. Egyptian-marked, and largely a reworking of Martini-Enfield parts. The Citadel arsenal took over the Enfield tooling, so the Citadel products were properly made. But they are usually terribly worn. None of them look like anything you would spend more than wallhanger money on. So a very careful inspection is mandatory.
Or, of course, it is a Khyber Pass home-brew. There are plenty of those about as well...
Good pics will give us the answer!
