There is a "Hi-Tensile Steel" sticker at bottom of seat tube. But no manufacturer listed. The clunker challenge is a great idea, however, i have a few projects in line a head this one, and limited time. Thanks for all the interest and advice, i will keep you updated. Also, i saw an almost same year bike, in old B.F. post, prolly '09 referenced above, Bike is a carbon copy except i believe that one is white/red, while mine appears white/orange.
