Much of the conventional wisdom regarding Siamese bayonets was clarified by research published in 2014 by Francis C. Allan, Patrick Hernandez, and Roger L. Wakelam in their book, The Siamese Mauser.

The M1879 Peabody-Martini rifle was primarily used by Romania. According to Steyr records, M1879 rifles were also made for export to overseas states during fiscal years 1879–80 and 1882–83. The quantities and overseas countries that received them are not shown in detail.

The bayonet used with the M1879 is patterned after the M1874 Gras bayonet, which was manufactured in huge numbers by Steyr. This 1883-dated example is from the 1882–83 production period.

According to Allan et al, at least 2,000 were purchased by Siam, where the rifle was referred to as the "Han Ree." Steyr records refer to the M1879 as the "Henry-Martini M79." This misnomer by Steyr may have contributed to the Siamese referring to the rifle as the Han Ree.

The Kodchasri property mark was the symbol of the Siamese Defense Division, forerunner of today's Thailand Ministry of Defense. The Kodchasri depicts a mythical animal, half lion and half elephant. The lion symbolizes bravery and the elephant strength. A large statue of the Kodchasri stands in front of the present-day Ministry of Defense headquarters in Bangkok.

According to Steyr sales records, 15,000 M1888 rifles were furnished to Siam, most in the 1890s. Some may have been used items, sold from Austrian military stocks. This example has the Austrian serial number on the crosspiece and a Siamese serial number on the pommel.

Originally known simply as "Type Mannlicher Long Rifles," they were re-designated Type 33 when Siam adopted the Buddhist Calendar in 1913. Buddhist Year 2433 corresponds to 1890.

According to Slovakian bayonet collector-researcher, Andrej 'Andy' Blazicek, the "IIQ" marking was Steyr's mark signifying "second quality."

The scabbard was made by the firm, Vogel & Noot of Wartberg. Vogel & Noot is still in business today, manufacturing ploughs and farm equipment.

Pommel: "1776" in Siamese characters

Scabbard (frog stud): "V&N"

These bayonets represent an enigma. Little is known about the origin and use of these double-edged bayonets. The “W” on the blade spine is believed to identify the maker as Weyersberg, Kirschbaum & Co.

Many books refer to these as the M1907, probably due to the bayonet's resemblance to the Chinese M1907 bayonet. However, Antwerp, Belgium arms dealer Jules Pire & Co. listed these in his 1905 catalog.

Although it is unclear when these were manufactured, a quantity were still in Germany when the First World War began in 1914. These were issued to Landsturm troops along with the Gewehr 88 and also as sidearms to machine gun crews.

Siam is documented as having imported 43,000 Mauser Gewehr 71's during the 1870s and 1880s. There is no documented Siamese import of the Gewehr 88. This bayonet’s association with the Gewehr 88 largely comes from how it was used in Germany, as an Ersatz Bayonet (Mery classified it as EB 149). 

This example has been refinished, as the original finish was in the white. The grip scales on this example have been replaced. The grip scales are secured with tiny screws set in escutcheons, similar to those found on early Japanese Type 30 bayonets. However, this is the result of a rework process done in Siamese arsenals.

This scabbard appears to be original, 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.

The characters on the ricasso say "R.S. 121" in Siamese, which represents the year 1903 on the Gregorian (western) 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 inspection marking on the pommel below the serial number is the Siamese character equivalent to the English letter B. It is believed that this symbol was of (then Major) Prince J.M.C. Bawordadej who oversaw production in Tokyo on behalf of the Royal Siamese Army. This identifies this bayonet as belonging to the first contract of 20,000 produced.

40,000 Type 45 rifles and bayonets were produced in1903 at the Imperial Japanese Army 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 scabbard has been refinished, as well, with the original rivets securing the throatpiece having been replaced with screws.

The Type 62 is a re-badged British Pattern 1907 bayonet. Siam purchased 10,000 SMLE rifles and Pattern 1907 bayonets from Britain in 1919 to equip the "Wild Tiger Corps," royal bodyguard of Vajiravudh, King Rama VI (reigned 1910–1925). The tiger figural on the ricasso is representative of the Wild Tiger Corps. Buddhist Year 2462 corresponds to 1919.

SMLE rifles and Pattern 1907 bayonets were taken from British stocks, refurbished by Birmingham Small Arms (BSA), and remarked with Siamese markings. The bayonets were shipped with standard steel-mounted leather scabbards. However, the leather rapidly deteriorated in the tropical climate, so the Siamese made a replacement steel scabbard body to which the original steel mounts were brazed.

This crude, unmarked M7 bayonet copy is believed to be from Thailand and to have been manufactured there. The fit and finish are poor, however, the bayonet and scabbard are serviceable.

The scabbard is a crude copy of the U.S. M8A1 scabbard. Examples are found with both green and black plastic scabbard bodies.

Military Assistance Program (MAP) records document that the U.S. provided Thailand with 84,308 M16A1 rifles and 43,368 M7 bayonets between 1966 and 1973; and 67,983 M8A1 scabbards between 1951 and 1972. Thailand also purchased 2,822 M16s from the U.S. via Foreign Military Sales and 55,000 directly from Colt.

The M16 has been replaced in major Thai forces by the Israeli Tavor assault rifle. However, the M16 is likely still widely used by regional, reserve, and police forces.
