I believe this to be a 250-c20 compressor. Parts number on tags are 6890529, 6876652, 6892764, 6876655. Item is being sold a pictured. I do not see any cracks or any major dings in any of the blades, and the bearing area looks to be smooth. This would be a good core for overhaul or good for ground use. sold as parts only with no returns. I have taken many pictures and rotated the compressor so that all sides are shown in the pictures. Happy offerding!
