Moderators I'm not sure if this is the right place to put this so feel free to move it..

I was wondering about the correct size for a .69 cal. wooden ammo arsenal box... I am considering on making them and was curious as to the proper demensions, I have viewed original .58 cal. boxes from the St. Louis arsenal but have yet to find originals for the .69 cal.

Thanks in advance,
