I made a trade (on another website) for some .30 Carbine brass. In with the cornucopia of brass was 10 cases with "LC 52" head stamp that were Berdan primed! I assume this is the Lake City Arsenal. I've never seen this before, though I don't make a habit of looking at early '50s .30 Carbine brass. See the picture below. What's the deal?
