I just received this very neat Siamese Type 66 Arisaka in trade, which I understand was purchased by the Siamese in the 1920s and was then used by them in their war with the French in 1940, alongside Japanese-suplus T-38s. Anyone know anything more about them? It's a very neat rifle, I'm surprised at all the small differences I notice when comparing it to my T-38. Aside from the obvious difference in rear sight, the bands are screwed in rather than spring retained, the cleaning rod has a different head and threads in rather than being spring retained, the barrel is a constant diameter without being stepped down for the bayonet muzzle ring, and the front sight isn't mounted on a band around the barrel. Most interestingly to me, the length of pull is about an inch shorter, I imagine because of the small stature of the average Thai soldier.
