Just picked up a rear wheel for this project (thanks @barneyguey!). Date code is L1, first quarter '42. Too early, but hopefully still "close enough" ? Strangely, the hub and its parts are nickel plated, but painted over O.D. Green. Also, the rim profile and the spoke nipples don't match the front wheel that came with the bike. Maybe this wheel is from a Cycletruck, or?
