Offered here is a rare Siamese / Thai Type 66 military rifle built on the Arisaka system. These rifles were part of Thailand’s early-20th-century military modernization and were produced within the Japanese arms manufacturing system, associated with the Tokyo Artillery Arsenal (Koishikawa Arsenal).

The Type 66 designation refers to the Buddhist Era year 2466 (1923). Historical estimates suggest approximately 50,000 rifles were produced or ordered for Siamese military contracts during the 1920s–1930s. Compared with contemporary European or Japanese service rifles, surviving examples are far less common and are considered rare among military firearms collectors.

Specifications

Model: Siamese / Thai Type 66
Action: Arisaka-system bolt action
Caliber: 8×52R Siamese
Magazine: Internal box magazine
Cleaning rod: Present
Dust cover: Intact
Condition: Action cycles smoothly and functions properly

Serial Numbers

Receiver serial: ๓๕๓๑ (3531)
Bolt root marking: ๕๓๑ (531)

The bolt root shows the last three digits of the receiver serial number, a common military numbering practice. Internal bolt components also show consistent numbering, indicating the rifle retains its original matching bolt assembly.

Condition

Bore appears relatively clean with visible rifling. The stock is structurally solid with no cracks and shows normal service wear. It retains the typical red base treatment with black lacquer finish commonly seen on Southeast Asian military rifles.

Note

While the rifle appears mechanically sound, it has not been test fired due to the lack of available 8×52R Siamese ammunition.
