NR/SR indexing shifters or my eyes playing tricks on me?

I have a collection of BQ next to the throne and was looking through the newest issue with the Japanese collectors. I noticed something that made me scratch my head and question what I was actually seeing. It looks like the last style of Record downtube shifters but with an indexed section where it mounts to the boss. Is this just two different shifters in a strange position or do these actually exist?

It's in between two sets of shift levers but a little out of focus. Each cable groove and hole for the ends line up in the same spot on each lever.

I spiced up the original photo just because.

Judging from the parts visible, it looks like it works through a whole different mechanism than Simplex ' s Retrofriction shifters. I suspect that it might Ave a ratcheting mechanism that acted as text one way friction clutch that still gets its resistance through friction material washers. Thus still the need for the tightening ears for periodical readjustment..... just my guess.....

Sort of...
they have internal bearings that are engaged when you upshift and disengaged when you downshift, with a friction-only mechanism as a consequence

Prototype Campagnolo "Dopler" retrofriction levers. No indexing!

Campy brought out their Dopler levers in 1987 as part of the C-Record gruppo. They made a plain friction lever version that looked the same which were far more common.



The Campy Dopler levers look really great and work pretty well but not quite as good as Simplex Retrofriction levers.

I get it, maybe a "ramp and bearing" design, just like a motorcycle's starter "sprag" clutch??
