Well Clark. Here is what I think. We know that Wagner modified Griswold patterns and then gave them a new catalog number. For instance, the number 10 camp oven, when it was made by Griswold in Erie, the number was 180, when it was made by Wagner, the pattern was modified and the number was changed to 310.
And the numbers on your pieces there, they all fit within Griswolds numbering system, and ain't even close to Wagner numbers. And we know that Griswold had bakelite handles. And we also know that not all pieces made by Griswold in Erie, Pa. had the word "Erie" or "EPU" on them.
SO, I think that these pieces you are showing here, were made by Griswold in Erie, Pa. before the merger with Wagner. Those are my thoughts. They are very nice pieces by the way. I was wondering if there was a way that I could beat you out of one of them. :-/
