Here's one that might be fun! If we could get the data plate info first, the other might fall into place easier as it might have instructions. The item looks like it might be container for some kind of artillery round - might be IJN

Your time and help is greatly appreciated!

Awesome - thank you Guy and Mr. Chen! So gentlemen do you think this translates more like a container to hold the gunpowder charge bag then to hold a fully assembled round?

From the wiki link Guy provided I may have answered my own question - "The 12.7 cm/50 Type 3 naval gun was a medium calibre naval gun of the Imperial Japanese Navy used during World War II. It was the standard weapon for Japanese destroyers between 1928 and 1944 (except Akizuki and Matsu classes). It has been credited as a true dual-purpose gun, but this was more a nominal capability than real as its bag propellant and need for hand ramming required the gun to be loaded at angles between 5–10° which dropped its rate of fire to a relatively slow 5–10 rounds per minute and its training speed of only 6° per second meant that it had a great deal of difficulty engaging enemy aircraft with any chance of success.
