Thank You for the help on getting this going.
I have this tandem with no I.D., no nunbers, nothing. The threads on the axle, and fork are not standard, or metric. The axles are 3/8"-20TPI. The front sprocket, axle, and bearings are held in with a U shaped bearing race made out of wood I beleive. All this is held in with a fiat square steel plate with 4 bolts holding it all in. The tandem looks like a 1930 Colson, only the rear steer rods have no linkadge. 2 rod with a loop on each end, and pivit points. Please help me I.D. this Tandem!!! Thanks!!!
