So far, I have two 9mm headstamps from this company, “R A I 9MMLUGER” and “RAI 08 9MM LUGER.” I have not seen any of their .45 or .38 Super headstamps yet.
Other Thai pistol-caliber headstamps are “T-A” and “THAI ARMS” representing that company, with some of it made by Sellier & Bellot in the Czech Republic, and “BM” for “Bullet Master.” We have the “BM” headstamp in both 9mm Para and .45 auto. It may (or may not) exist in other calibers. A lot of Thai ammo seen has been loaded in current Winchester cases, and a .45 Auto with only the caliber marking - no factory designator - and also made by Sellier & Bellot, has been found in Thailand.
IPSC is probably the cause of so many countries making and using .38 Super now. It used to be that the .38 ACP/38 Super case type was popular in exactly two countries on earth, the USA, and perhaps to even a greater shooter per capita level, Mexico. Now, seems like the cartridge is made in many places, with Thailand and the Philippines coming immediately to mind.
Interesting how a relatively old, and not hugely successful cartridge can become resurrected by the advent of a new shooting sport. Of course, that has happened with many of the old U.S. Revolver and rifle cartridges due to Cowboy Action Shooting and its off-shoots (no pun intended).
Thai boxes are quite colorful. I have a number of them from different makers and in different calibers. One of these days before long, I will scan them all for a thread on them.
