Replacement Fork on Balloon Model

I broke the steer tube on a 1938 26" wheel frame. Everything on the bike indicates it is a balloon frame the first year they were made. However this fork doesnt have to correct curve and has a deep chrome cap over the crown. The catalogue says the crown is aupposed to be enameled. 

From looking through photos it looks like the fork is a generic replacement or maybe from a late 40's or 50's balloon ccm but i dont really know. Maybe it is original?

Anybody see a fork like this around?

Thanks in advance
