Scarce Unmodified Siamese Type 45 Mauser Bayonet with its original Blued Steel Scabbard

Here on offer is a scarce original untouched version of a Siamese Type 45 Mauser bayonet with its original blued steel scabbard.

The Siamese Type 45 bayonet was produced in Japan under license from Mauser in Germany. 40,000 Type 45 rifles and bayonets were produced in 1903 at the Imperial Japanese Arsenal at Tokyo (Kowisikawa).

Siam wanted Mauser to produce them, however, Mauser was inundated with large rifle orders for the German and Turkish governments, so licensed production in Japan.

The Siamese Type 45 bayonet was the first Mauser bayonet to conform to what was known in the west as the M1904. Because of this, the Siamese Type 45 bayonet and M1904 Mauser bayonet are interchangeable.


The single-edged blade has a flat spine above a deep single fuller. The blade is in great condition but now shows some age staining to the finish, which may polish bright.

The ricasso bears Siamese characters, translated as; "R.S. 121." This represents the year of manufacture, 1903 in the Gregorian calendar. "R.S. 121" is an abbreviation for Rattanakosin Sok 121. This refers to the 121st year of the Rattanakosin Era, which began with the founding of Bangkok in 1782. The bayonet was re-designated Type 45 when Siam adopted the Buddhist Calendar in 1913. Bhuddist Year 2445 corresponds to 1903.

The steel cross guard/muzzle ring and pommel are in very good condition and the press stud mechanism is in crisp working order.

The end of the pommel is stamped with a serial number in Siamese.

The wooden grip scales on this example have not have been replaced, as they are secured using the original method of circular nuts through which a bolt was threaded, then cut off and ground flush. The grip does now have some dings and wear consistent with its age and use.

The scabbard is in excellent condition, retaining most of its original blueing with just some light frog wear to the upper third. There is also a tiny ding on the front.

This scabbard is an original version, never having been disassembled or refinished. The scabbard throat is unique in having a depression that allows the scabbard to remain on the bayonet when fixed to the rifle.

This is just a fine and genuine example of an early unmodified or refurbished bayonet.

The blade measures 9.75” (24.7cm) and the whole is 14.6” (37cm) long.

It weighs 530g.
