Yeap, sorry Terry...it was designed in 1968. The first two numbers stand for the year it was made and the last two numbers tell us it was the 12th design for that year. But, this numbering system didn't start until 1953. Winslow Anderson and Wayne Husted came up with the numbering system that Blenko started using. Prior to this other methods were used and today they have changed again. Since Blenko hasn't had a designer in a few years they have pulled old molds and re-made older pieces. Your pitcher is one of the ones they have since remade. It was remade in 2001 with the number 2118 and they even made it in a frosted version, 2118-F. Hope this helps.
