Well, I think it started out with Griswold, and then Griswold changed the "ERIE" and went to something totally new, you can see this from the time line in the BB. And then I'd say Wagner got this pattern, and used it awhile and then sold it to Wapak who modified the pattern to fit their own needs. The raised J is interesting. Bear in mind that Wapak went out of business in 1935 or there abouts, and all their, already modified, patterns went somewhere, probably to several manufacturers at that time. It would be interesting to see just who was in business after 1935, that could have possible wound up with the Wapak patterns. We know, or can assume, that Wagner or Griswold did not want them back, so, they probably went to small foundries all over the US at that time. I'm saying this sounds plausible.
