Identify this hub (similar to a Sturmey Archer rear internal gear hub w/ drum brake) I recently came across the auction of  an old Gazelle city bike. It is equipped with rear internal gear hub with drum brake which looks like Sturmey Archer 3 gear hub. But this hub has two shifting cables (one on each side, going to the internal hub) and very strange shifters, which I guess are not original. 

The auction description states that this is 3 gear hub.

I've seen Sachs Pentasport 5 hear hub with similar shifting design, so I suppose it might be something similar.

Please, help my curiosity and identify the model of the hub.




EDIT
on the handlebar I've noticed some kind of gear shifting instruction, which suggest there is indeed 5 gears.


Auction
Appearance is alloy shell and 70mm drum which would be a Sturmey-Archer AT 5 , which was made mid 80's thru late 90's with dual lever shifters . A version was also made with just 3 gears .
