Just love these! I have been fortunate to acquire a good number of these wonderful old J.H. Weston LRis. These are from various mold styles. Some of the tabs are obviously different! Note too, the embossing on the lower center, and lower right pieces. The glass bodies are mostly the same, but on the center one you read: CIN.O (yeah, they embossed all of these upside-down!). On the lower right one, you read: J.H. WESTON. (also upside-down). I got my first one of these sometime in the early 1980s. More cool OLD glass.
