One of the bikes is in the museum at Ft Stewart, Georgia. It's a Peugeot, With the same sort of lugs as a UO-8, but they claim it's 1950's, which could be true. Most of the factory components are gone, along with much of the paint. But it was a lightweight, at least before they welded on the racks for carrying loads of supplies. (think channel iron, not Herse.)
