Wanted: WW II era Japanese engine cylinder for a memorial

[Kaigun Fan]

Hello,

I am trying to help out a Japanese friend. He is looking for a complete WW II era Japanese engine cylinder for a small memorial dedicated to a local former IJA WW II air base. I guess a local elderly who use to work there during the war runs a restaurant that some veterans meet at. My buddy is gathering some artifacts for a display at this restaurant.

Any leads would be appreciated - it doesn't matter which motor either but he wants a complete cylinder with a piston, etc.

Thanks,

Ron
