Late 1960s to around 1976 Diner and Anchor Hocking markings This is a shell series marking. I obtained it as dead stock in a box and kept it carefully. The box was worn out, so I had to dispose of it. I am selling it to declutter. This is from the time when the 1950s Fire King era ended and the company name only was used. I love the translucent look, like a seashell. I haven't washed it, so there are cardboard marks and tape residue. I will wash it as much as possible before shipping.
