Need help to identify this diff

[r33420]

Hey guys I need some help identifying this diff I pulled out of my r33. I bought a stock r33 diff and got them swapped because this one was a nuisance to daily drive. Every time I turned at low speed the car would bounce/shudder.

When I bought the car the guy said it had a Nismo 1.5 Way Diff. I thought something was wrong with my car then after googling the symptoms I found that those diffs are supposed to make heaps of noise at low speed turns so I bought a stock r33 diff and got that put in.

So now I want to sell the "Nismo 1.5 Way" but I want to make sure it is one so I don't rip anyone off.

What do you guys think? I can take more photos if you can't tell from these.

Cheers.

The key pic internally is to take the inside of the hole you can just see in the first pic. Assuming its a mechanical centre there are ramps inside that determine if it's 1, 2 or 1.5 way, they look like |/, \/, or a halfway between those 2 respectively.  

Also there will be a ratio stamped on the main gear as well, something like 37:9 which is the 4.11 diff. edit, cancel that, I can see you have that in the 3rd pic

I don't know how to tell the brand of the centre, others might, but personally I don't think it matters too much
