Westmoreland Glass used the maker's mark of a diamond with a W superimposed on the diamond from 1949-1989. That does not really narrow it down much but when one considers the Earth is 5 billion years old it is fairly close.
This is on the bright side for Vaseline glass which means later Vaseline glass. Noted that before I bought it but the price was still acceptable. I prefer the earlier EAPG Vaseline glass pieces but that is not set in stone.
It is something I have not seen before and I can not find an exact match on the net.
