PICS help identify this chunk section posi or not and value of it

yea i didnt think this was a sure grip sense it has no springs cones or spool but just making sure and i can tell him what every one else says

Offer him 50 bucks then strip it for parts, the pinion and crown gear stay together as they are a matched set and someone was on here a week ago looking for used side gears. The bare outer housing with bearing caps is probably worth $75.
