Kitty Cat rifle
I have one of those rifles too. It has a cat's head motif on the receiver band. The language is Siamese. Around the cat's face it says 'Mark Rama VI, BE2462' (Buddist Era 2462).
King Vajiravualh Rama VI was educated in England and had training in the British Army. He reigned Siame 1910-1925 and established his Wild Tiger Corps in 1911. Not suprisingly he bought British kit for his troops. He ordered 10000 rifles with slings and bayonets at a cost of 76,625 pounds.
The rifles are full military spec Mk.III* but have no martial markings. It should have BSA marked on left wrist and stacked rifles on barrel knox form, but that would be about the only engrish on it.
Mine has a matching P.07 bayonet with a pussycat head on the riccasso. The tropical climate was hell on the leather scabbards and it is common to see a sheet metal replacement for the leather. Mine has replacement grips made from local wood too.
Apparantly a bunch of these rifles were imported into North America in the sixties through the usual surplus channels and sold along with the other imports. Not really rare, but a nice find. Most have a beautiful dark walnut, and all the ones that I have seen have really good bores.
