[e30vert]

I was wondering if anybody could let me know whats up with this ? I have the chance to buy this turbo from a friend {more a customer at work} says he bought it for a VW he had but daughter wrecked. I have included pics. I was wanting to install it on my 89 e30 325 & it is stock. the pics I have seen of other turbos have tags riveted to fan body, this has it engraved ? any help is much appreciated.
