No mystery city, it says it right on the plate. They were made in Baker Oregon. That's a town near me, a couple hours or so out of Boise, Idaho.
Not trying to be mysterious, just wanted to not throw this out if it was desirable to someone. I don't understand collectors very well, and I've seen here mr Lugnutz collects military hardware, and is quite knowledgeable. I scrap a lot of crud that guys on here drool over, because it's not worth postage and a few dollars. I was just trying to see if this was in that category, and should go in the aluminum recylcle or not. Hate scrapping things that someone genuinely collects and wants. At least old stuff that once gone, is gone. Have no qualms scrapping cheap current stuff that's just not worth postage and effort.
