axle id

Picked up this axle looks like maybe a chevy but not sure the kingpins are smaller than th 47-55 p/u axle but I was thinking maybe gm car? It also appears to have been dropped in the past.
There is also a series of casting numbers on the bends of the axle.
Anybody have a idea what it is?

 

It's a Chevrolet ... '33 Eagle (Master), all '34 - '40 1/2 ton. Looks like it's dropped 2 1/2"

 

Thanks @ least now I know what I have here.
