Siamese Type 46 Long Rifle

According to the Thai government the manufacturing of the weapon was to be acomplished at the Royal Siamese Arsenal in Bangkok but it did not have the facilities to manufacture the barrelled actions so they placed two orders for two batches of 20,000 each of rifles (40,000) and one contract for 10,000 carbines to their Asian ally, Japan at the Imperial Japanese Army Arsenal called "Tokyo Artillery Arsenal" located in the Kowisikawa District of Tokyo. This rifle is similar to Japanese M-35

Ammunition/Modification
The weapon was originally chambered for the 8x50Rmm Siamese Type 45 (2445) cartridge which was adopted in the year 1902 a full year before adopting the Type 46 Long Rifle, these were for used in the Steyr made Model 95 Mannlicher Rifle that was exported to Siam. The bullet was a round nosed, lead cored, cupro-nickel clad, full metal jacket design that weighed 237 grains and had a diameter of .321-inch with an approximate muzzle velocity of 2050 fps. The cartridge case was made of brass with a Berdan primer and on the bottom of the cartridge case it is marked with the numbers 45 in Siamese script. Only ball bullets were used. This cartridge was made in both Japan and was the first cartridge to be loaded at the National Arsenal in Bangkok. Note: The Siamese Type 45 is not interchangeable with the Austrian 8x50Rmm cartridge even though that round was used as a basis for the development of the Siamese Type 45 cartridge. In the early 1920's the Siamese wanted to upgrade the Type 45 cartridge to a more powerful and pointed type of round for use in their Browning F.N., Vickers and Madsen Machine Guns and the Type 45 was not suitable for this, thus they developed the 8x52Rmm Siamese Type 66 cartridge. The 8x52Rmm Siamese Type 66 cartridge was adopted in 1923 (2466), using a spitzer boat-tail bullet, lead cored, a gilding-metal or copper-washed steel jacket design that weighed 181 grains and had a diameter of .323-inch with a muzzle velocity of 2250 fps. The cartridge case was made of brass with a Berdan and later Boxer primer and on the bottom of the cartridge case it is marked with the numbers 66 in Siamese script. Ammunition was also made in Tracer, Armor Piercing (AP) and Armor Piercing Incendiary (API). This cartridge was made at the National Arsenal in Bangkok until 1953, Japan, England (Kynoch), Denmark and Finland (Sako).

The Japanese M-35 6.5mm Rifle (1902)

It was Kijiro Nambu's first rifle and it was made for the Navy. It has a dust cover on the action and has physical characteristics which clearly show the mechanical transition from the M-30 to the M-38 rifles. Only 36,000 were manufactured at Tokyo Arsenal, and some were exported to Siam (Thailand). This rifle is similar in size to the M-30 Rifle.
