I'm still working on it... but it's clean enough to get some pics... appears to be a 'set'... the '8's match... don't think I've ever seen basting drippers quite like this before... dimpled like BSR, but in a consistent pattern. the bottom has a full inset heat ring, raised '12' as a molder's mark and some sort of incised marking from the pattern... handle doesn't resemble anything else either
