Kawanishi H8K2 Emily (Aircraft Test Set)
This is a WWII Japanese Navy aircraft test set, I was told it was for the Kawanishi H8K "Emily" aircraft, but I have no idea for what. The box is wood and measures 12 inches by 10 inches and 7.5 inches deep. The from metal plate has some corrosion, but other then that it is in good condition. I do not know if it works or how it works.
