This is a 1st Section project that has taken a long time and we're real excited to see it finally complete, and done so dead nuts correct. 
 
Friction primers came in tin boxes of 100, especially in the first half of the war. We copied an original box down to the single coat of thinned japanning that gives it a streaky brown glaze looking finish.
 
They're great for multiple purposes, as aside from carrying friction primers in your limber chest, a second can carry loose fuzes as the manual suggests. There's a lot of expensive die work in these, fiddly tin boxes, and real japanning ain't cheap, but you won't be able to find anything closer to an original.
