Thanks for the help guys was hoping it was a aftermarket LSD but look like I am going to have to keep looking

I pulled a r200 form a 87 turbo 300zx today. When i cracked it open did not look like a lsd or open diff . I was hoping someone could help me id it when i held the the drive shaft and spun one cv axle the other spun in the opposite direction when i spun the drive shaft the only one cv axle spun it did not have fins on the back of the case. im hoping its a lsd or vlsd all the r200s i came across so far you can see the spider gears very easy thanks for the help
