Thanks, Adam. Yep, while the condition makes some of digits difficult to confirm, the second is more likely an H than a 4. I bought the bike about a year ago, and now it's time for the fun to begin! Tires are the Davis Deluxe (possibly original), pedals and grips are both Western Flyer...so my goal for the bike is preservation. Still need to determine the original light. According to a '52-'53 Western Auto Catalog, during those years they came with a Rocket Ray.
