Japanese Naval Artillery shell fuse JF-550

A special thanks to the collector who sent me some information on this item.

It is a type 89 Combustion time fuse for a H.E. 75mm or 105mm  Anti aircraft gun.

Japanese Naval artillery shell fuse with container and take home papers. I don’t know what type or size of gun this was for, but it has to be fairly large. It has adjustments and settings for a couple of things and the machining is incredible.
