RoadMaster Boy bicycle ID Help

[FlordiaRust]

I just got this old RoadMaster and can not find the serial number on it for a exact year.The rear wheel says New Departure and has a skip tooth the sprocket I do is a Lazy heart style and the tank looks alot older than the 1950's style of Roadmasters I viewed.

I believe that's early postwar, CWC usually used that chainring on Western Flyers. -Adam
