Hot Rods ID this ten bolt rearend?

Can anyone ID this ten bolt rearend? The casting numbers were ground off when it was chromed years ago and I’m not seeing anything with this diff cover. Trying to figure out drum brakes for it. Thanks

 

A pic of the front of the pinion carrier would help. My wild guess is shoebox Ford.

 

Here's a start.

 

I am thinking 50s Oldsmobile

 

I don't know why I wasn't thinking to check the hoghead for casting numbers. It's been one of those days. I've got a 513281 in one place with a large 5 underneath it, and a C240 in another place. That Olds sure looks like it.

 

I think 50 Olds is the answer. Thanks all!

 

Show us a photo of the front of the pumpkin. From the little I can see, it’s a Pontiac or Olds.
