Got a new headstampv- "Wilson" .45 acp brass today

Shot a match this morning, and a shooter who did not reload gave me his brass. Wilson headstamp. I thought it was a new ammo company, but he told me it was "Wilson" as in "Wilson Combat". Anyway, I gratefully accepted the brass, but I'm curious to find out who makes brass with this headstamp. Any ideas?

Starline, huh? I'll weigh the brass. Starline .45 cases are much lighter than the rest of my stash, so if the Wlsons are light as well, it will be a clue.
