Stopped off at the local Goodwill store on my way home this afternoon, and was lucky enough to find a mint condition set of "Early American" pattern Pyrex mixing bowls. They were still in the original box, with all of the original packing materials. The box had been opened at some point, but the bowls have never been used. I was not familiar with the pattern, so I looked it up on line an found that it was manufactured from 1962-1971. Is there any way to tell the year that this particular set was made? I haven't been able to find a date on the box, or the bowls. No serial numbers that I can find either.
