[MENTION=381793]gugie[/MENTION] thanks... there's another few productive hours of my life down the drain.

amazing stuff! I'm rather overwhelmed by the Aviac aluminum rando bike. ....

It's not enough that it appears to be an early aluminum bike with cast(?) aluminum lugs and aluminum tubes. The assorted components are captivating too!
For instance, I'm intrigued by the brakes, and especially the mechanism used to spread the upper ends of the beams....

Even the little details, like the shroud over the dynamo's roller wheel are cool!

Boy, just when you think you've seen some remarkable stuff already, along comes a collection like this that makes you stop in your tracks. Thanks for sharing!
