Thanks , Ben.
They appear to be canvas bags, rectangular in shape and possibly a plywood or metal box for crushable items. The box looks larger than a 12-unit Aid Box - possibly with a paper label for contents.
Anyone have something like this?
I believe one of my two is marked "MED 1" stencilled on the front flap - no other unit markings. I'll look for makers marks inside when I re-open the vault next week. The other one is un-marked.
