This frame, which I’ve never heard of, came up for sale in my area. I did a Forum search and found 2 posts asking the same question with no responses. I’ll ask again. Has anyone ever heard of a JP bike brand called “Silver Eagle”?

Not sure - But at least it might be worth the parts...

dropouts look cheap, pretty good indicator of quality of the rest of the bike. Pedals too. I'd pass on that one.
