I picked this up in the U.S. on a recent driving trip.  Didn’t recognize it, but it was only $5.50 so I thought I’d bring it home to identify.

So far the closest I have come was to identify it as New Martinsville Florentine #29, Teardrop Blank, made in the 1940-1944 range.

But I’m not entirely confident in this ID.  Although etches vary depending upon the piece that is made, this one seems close….but no cigar.  Photos I’ve seen of the etch show a dangling bunch of grapes.

I don’t have any books on New Martinsville (yet) so I have no targeted reference text.  For the meantime, I’m going to “believe” that my ID is correct, but I’ll keep looking!
