Help Indentify Rear-End

Can someone indentify this rear-end for me thanks..
30 Model A

 

FROM THE SMALL PICS, LOOKS LIKE 50ish OLDSMOBILE

 

it's really small must be a yugo!

 

I've got a identical one laying next to my garage. I've never researched exactly what it is, but I'm pretty sure it's a late 40s early 50s Olds- 10 spline axles but the axle bearing ends appear to be the same as the later 57-64 rears.
