Help identify R200 LSD brand

[roolis]

Just got offered R200 diff,i know that its 4.08 ratio diff,it came from S14,but seller cant tell what brand is that 2 way LSD,anybody can tell what brand it is?by Google it looks close to Nismo,but not sure,thats all the pictures i got:

The markings on the crownwheel make no difference because they are Nissan parts regardless of the origin of the diff centre.

The fully machined surface on the pumpkin does indeed make it look like Nismo.  Beyond that, it's going to be too hard to be 100% sure.  There may just be another brand that is machined like that, not that I know of any.

after more searching,i found this https://my350z.com/forum/engine-drivetrain-and-forced-induction-diy/412098-nismo-diff-home-install-pics.html

and it looks realy same,as for a lot of googling,only Nismo ones have like fabric welding on the end of lsd,where you see such dark line,othe machined ones are shiny all the way,like Kaaz

If its exactly the one,then its very good for me,cause i even want to make it 1.5 with medium lock

bought it and took it apart,so thats what we have

its defo Nismo lsd,it was set to 2 way,so i will change it to 1.5 way

just one difference,no lock adjustment bolt as in topic that i have shared before
