Rolleiflex 6002 "Property of Rollei"?

Hey there. Just found a Rolleiflex 6002 on craigslist that was originally picked up at an estate sale from a deceased photographer. On the front of the camera, under the lens, it says "Service Equipment" and then under that "Property of Rollei". I have never seen anything like this on one of these cameras. I imagine this meant it was original property of the company at some point; does anyone know anything about this?? Pictures attached.

 

Photo links dont work for me in OP. Here they are:

The ownership label:
image1-1

the camera:
image0-1

 

Interesting, maybe the original photographer worked for Rollei.

Might try contacting the Rollei club.....?

I'm guessing it lived in a Rollei service center before escaping to market. Lens tester? Have seen similarly marked Nikon bodies.
