Aristo 870 Multilog pocket slide rule magnifier cursor 1970 Germany

Smaller pocket slide rule by Aristo from Germany. This is the model 870 Multilog that comes with an unusual magnifying cursor, which was a more expensive upgrade and not often seen on pocket models.It also comes in its original Aristo signed leather pouch. Slide rule, cursor and pouch are all complete and in good condition with clear signs of use, no cracks. I also noticed the magnifiers do not line up exactly but the hairlines do!. The slide rule measures 16,5 cm 6 1/2 inches long. See the attached video on how to work your vintage man tool : slide rule operation instructions!
