one of the things wrong in our hobby...mis-information, which is much worse than no information. This is an example of what has happened in our Hobby (and likely many others)...the repeating of the wrong information, with no one questioning the source(s), or asking to see any context.
Looking on Worthpoint, type in Erie can opener, and you'll see several past sales. The problem is most claim the can opener stamped ERIE was made by Griswold. Worse yet, there are supposed sites, writers, societies, who should be leading by example, yet they even have ones who have collected for some time, claim to be well versed in their focus, but yet insisting on hyping..."I own one of these "rare" pieces made by so and so". In past references/books, in their defense, we now have access to much more and easier to find data than they did years ago. Does no one even bother to take a good hard look at this kind of thing...even done in print, etc.. ? I ran across this and decided I do not buy into the maker of the Erie can opener.
FIRST and foremost, just because it says ERIE does not mean it was made by Griswold, or even made in Erie, Pa.
Secondly- Looking at the pictures, one can clearly see the Rd 227761 No on the piece...THAT Rd is an indicator that it is a Registered Design, specifically from U.K./Britain/ English.
Thirdly: First newspaper I read from England mentioning the Erie can opener tells the story.
I can only plead that Please, slow down, let us not jump to conclusion without the proper vetting of the data. Nothing wrong with wishful thinking, that perhaps, eureka, we just found a "rare" piece made by Griswold, or any of our beloved foundries, but please, tread carefully...question everything and read/research, then read and research again. Again, the only thing worse than no information is the wrong information...FWIW Edit to add: The nice thing about our hobby is, we do get to change or add to our data bases...it's a continuing learning curve as time goes on.

What I read was a on another site on the internet, claiming this was made in the 1930's, by Griswold Mfg. .. Well, how about late 1800's, in England.
