Need someone to ID an axle for me

[sevenslats]

It's sitting in my driveway in North Pole. 10,000 miles away from where I type this.
I have pictures, but not of the diff cover.

I think it is a Sterling 10.25, full float.
It is supposed to have been rebuilt recently.

I need to know the model (there's a chance it's a D60), and the condition of the seals, bearings, and brakes.
I'm shopping for parts, and need to know exaclty what I don't need to buy.
