Juvela - wow! I mean, WOW again! You have a singular talent for identifying frames! That pretty much nails it. Since I got this frame in NYC, I'm wondering if it was a survivor of the original American Youth Hostel herd!

Very interesting how it could be a Lygie as well. I realize that without the original finish and transfers, we may never know. And the front fork may or may not have anything to do with the mystery. Perhaps I should send some images to Lonnie, regardless?
Thank you for the the vivid pic and the Atala cross table. Great reference, that.
