Bought this in an auction lot so I don't know a lot about it. I believe it came off a late 1980s 1.8L 16v engine. It spins nice and easy.  The fan and pulley were taken off and painted. The alternator was all wrapped up in tape when I got it, I guess for protection. There is tape residue on the outside of the case, it is somewhat sticky. The identification tag is gone.  It is UNTESTED, so I listed it for parts not working. Selling as is as shown, no returns.  I believe it is a Bosch alternator. Please inspect all photos for details.
