I'm considering selling this truss frame but before I do I kinda wanted to i.d. it. This is a 20" frame made for 28" wood wheels. It measures, seat tube 20", top tube 22-1/2", and down tube 23-1/2". The head badge screws on this measure 2-1/2" apart horizontally, same as a Mead Ranger badge but could be anything. Original color appears to have been black. The BB cups on this seem to be deeper than average and the insides are square at the inside back rather than shaped round like most others. Any ideas?
