Help with Kanji on Unknown Wood Box

[monkeyboy]

Hello, I'm hoping for help with the kanji on the pictured wood box. I can make out type 1, large model, power, gun and model 22, but I'm lost after that. It's approximately 19 3/4" long, 8 1/2" wide and 3 1/2" high. There are a couple of ink stamps in the lid but I don't recognize them. I presume naval use given the grey color. Thank you for your help.

Thank you very much Guy! Your help is always appreciated. Now the quest to figure out what gun is indicated. An online search turned up nothing concrete.

Oops, Guy forgot a character!

動力銃架 = dōryoku jūga = power gun mount, of airplane.

Thomas, thank you for the additional help! I imagine the box relates to a Type 1 flexible aircraft MG. https://www.youtube.com/watch?v=VewqEy9zI04

The powered gun mount was used by the navy on the Betty bomber 一式陸上攻撃機 and maybe other airplanes. The machine gun used in the mount was the 20mm Type 99.
