It looks like a steel toolbox!
			 
			 
			
		
		
		
			
			The Lewis ammo box holds either 4 or 6 magazines in two stacks. It has a leather handle on the front, and a squeeze type clip to hold the lid down. There is a divider in the middle, but that has been removed from mine. 
There are remnants of felt padding too. 
 
I have seen another one with the stencilling along the front 
 
I'll post some photos, and get the measurements
