3rd member and locker ID: WTF is this thing?

I was told this came from an 82 toyota, but does not look like any toyota diff.
there's some sort of traction adder in it, I don't know if it's factory or aftermarket, but the fact that the housing for it is sand cast instead of machined makes me think it's a factory item, but what do I know?

careful: big pics
http://www.dana60.com/sundowner/diff2.JPG
http://www.dana60.com/sundowner/DIFF1.JPG

here are the specifics:

it's bigger than a toy pig, a lot bigger
the ring gear has a total outer diameter of 8.5"
both bearing caps are embossed with D3048
there are 10 holes in the flange for the pig to mount to the housing.
there are no screw adjusters for the carrier bearings, I can see that the carrier bearings are shimmed from the inside like a dana axle.
there are no other markings on the case indicating who made it (argh.)

I forgot to mention that the ring gear bolts are graded at 10.9(metric)
might be eaton if they made drop-outs after most ofthe OEM's went metric.

could it be something like a Nissan or a Rover?

gear ratio is 4.56:1

That is not an eaton. It looks like one of the axles in one of the dually toyota U-Haul trucks.

I missed something, it is not an Eaton. I have not seen an eaton with a pinion flange

It has to be out of a nissan or LR, definately not yota, the flange is very different from a yota flange, the inner diameter is too large where the driveshaft bolts to, plus the webbing is different from both a 4cyl and turbo/v6 diff housing

a dually yota 1ton rear has the same pig as a turbo/6ycl one

I've been looking for pics of different 3rds,
but the rover 3rds have an external pinion bearing support like a 14b or a ford, so they're not options, and the nissan 3rds have screw-in carrier bearing adjusters with lock pins like a toyota, so they're out.
I'm trying ot find pics of an isuzu 3rd.

Here's an article with some pix:

That looks like the factory clutch-drive limited slip. That might have some value to the right fella.... the diff itself isn't very marketable to someone without an Isuzu axle to stuff it into.
