Help on arisaka barrel threads

[riceone]

Jmore, that explains the 38's that I have seen with the SKS rear and front sights and folding bayonet. I also have two that the Chinese bored the T38 barrel and rechambered to 7.62x39, one has a block in the rear of the magazine for the shorter cartridge and the other has a shoulder block to hold the cartridges to the rear. Have two 38 carbine rebored and rechambered to 8x57 and two long rifles did the same way. No end to what was done to Japanese rifles after WW11. riceone
