Manchukuo was a Japanese puppet province so its likely a crude copy of a Japanese grenade. They also made copies of Arisaka bayonets and they were crude to say the least.

Jibarium, that is an interesting grenade. The Japanese made similar last ditch grenades in the Philippines. If you decide to sell it someday I might be interested.

Thank you..

Hi JBC99:
In fact, this grenade is not my collection. This is my friend who asked me to disassemble and remove the explosive, because he did not have the right tools and methods to disassemble it. This is an exhibit for his museum. I want to buy it, but my friend didn't agree.

This is a picture I took after disassembly.
