Thanks guys.I swapped fenders with the step thru in the background.They were alot better.I'm going to steel wool it and pull the crank, grease it and the axel and head set bearings,throw a new set of whites on it and try to cover that cool seat and go.As far as I can tell It is a 1950 Columbia according to the serial # N7982.No headbadge.The step thru is a 1955 Goodyear Hi-way Patrol.
