Trying to determine the year for a Schwinn Cycle Truck. Number at base: CO 5 13 48. Anyone know how to date the bike?

That's not the serial number. Schwinn stamped the numbers before the bike was painted. Are there more numbers under the crank?
Very interesting frame.

Thank you for the information. I'll have to search the frame again for a serial number tomorrow. I've been unable to find a reference for a Schwinn Cycle Truck frame that matches this one. Perhaps it was a custom order?

I've never seen a CT frame like that but maybe @REC has. Nice job if it was a custom. It has the long brake arm and has a dimpled chain stay for the Whizzer motors. Factory modified Whizzer CT frame maybe?

That is a Pow'r-Truck frame. Look up Schwinncoll's posts regarding his restoration currently underway. There should be a proper serial number under the crank housing or on the left rear dropout. It will be post-war, and usually '53 or earlier.

I'm not familiar with that type of frame either. It's a nice looking bike. Looks like its ready to deliver pizza with that box. Have fun.

Welcome to the CABE by the way...

Hand stamped. Could CO be C & O Shoe repair and 5 13 48 just be the date May 13, 1948? Maybe the day the business opened or the day they got the delivery bike.
