The ZH-29 is a semi-automatic rifle developed in Czechoslovakia in 1929, and used by the Chinese National Revolutionary Army. It was later iterated on and upgraded to the ZH-32.

It is chambered in 8mm Mauser (aka 7.92×57mm Mauser). It is a gas-operated semi-automatic rifle with a tilting-bolt locking system.

In China, Zhang Zuolin’s army received 100 ZH-32 rifles, and the provincial troops of Guangdong received 33 ZH-32 rifles.

Interestingly the inscription on the buttstock is actually in Japanese. It looks like some of the characters are worn down, but it seems to say チェッコ小銃 — which translates to ‘Czechoslovakian Rifle’.
