40mm artillery piece
picked up the 40mm at a fleamarket for $8. here's some more pics of the 40mm:
bottom of case with dates, etc. anyone able to ID this, give any info?
close up of primer and writing around it.
stamped writing on the side.
and, upon inspecion with a light, the primer rises up in the center of the bottom of the case like the post on a HydraShok bullet. any reason? perhaps better ignition time?
