Technical help ID this axle

I have the chance to buy a trailer with this under it. It's missing the brakes. There is a second trailer with a Durant Star axle, but that has no drop and and hard to get replacement parts. Thanks in advance.




P.S. yes I've been gone too long

 

Chrysler double dip tube axle?

 

^^^ that's my thoughts too

 

I knew it looked familiar, thanks guys.
