I've come across a Linear with "Um Num" on the frame. Anyone familiar
with this 'bent? Interested in knowing how old it is, what the cost
was new and approximate value in good condition today.

If you have not already, see http://129.79.22.9/linear/.

When I stopped at the U.S. Route 52 Mississippi overlook in Guttenberg,
Iowa, there was a holder with tourist brochures. In the brochure, it
stated that Guttenberg [1] was the home of Linear, "The World's Most
Comfortable Bicycle".

[1] Linear production has since been moved to New York State under
different ownership.
