I looked into the Gevenalle a couple of years ago to convert an MTB with 10sp Dynasys derailleurs to a drop bar to do a tour with it. They supposedly made them but were out of stock, and they were going to be expensive, more than the original setup. I ultimately bought SQ Labs bar inners, which give me a drop bar thumb hook position on the otherwise flat bar setup. I can shift and brake without moving my hands. This won't help the OP though since he already has drop bars.

Not a great picture, but one can see the b-screw is almost entirely outside the diameter of the dropout.
Slightly better picture.
Thinking one of these in the proper diameter might work.

It's a custom frame. Lineage unknown, and I don't know enough about dropouts to identify the dropouts visually.

Another challenge!!
Where does one find lever clamps in different sizes? All I can find are 22.2mm clamps. The usual suspects Universal Cycles, Problem Solvers, etc..... don't have much that are labeled with sizes.
I swear the Campy clamp used to fit - honest.

Are you asking where to get the correct parts for the model brake lever you have?

I was going to suggest the Genevalle shifters also but… first I get the coffee.

I was just using your post as a reference point, not trying to correct you. I'm sorry anybody misunderstood. But, yeah, the levers are the most costly part of the system, so it's kind of silly to built around the derailleurs.

And why not bar-end shifters? They would appear to be easier to actuate than any of these brake-hood attachments, providing you can get your hands on the drops.

Guess I’ll “borrow” one from a good pair. Pinky swear I’ll replace it 🤪

I didn’t care for friction shifting for the rear. But I’m running Ultegra index DT levers now and it is much better with the hand gyrations. The spring loaded left lever makes shifting a triple a breeze.

I’m running a set of Kelly’s. When I first got them I didn’t care for them but years later I dug them out and I think they are there to stay.

But Kelly's with Simplex Retrofriction and the right RD could work well.

I've read the thread, but might have missed something or misunderstood the ultimate goal. I know that DT shifters are to be avoided and that there is a Campy RD with a Shimano rear hub.
If it were my bike, I'd get some friction bar end shifters, maybe. Except I once tried 9 speed with friction shifting and the close spaces between the cassette sprockets just made it a little too fussy for me - and I "grew" up for over 20 years with friction shifting.
So, I personally would go for indexing with 9 speed, but YMMV. I would replace the RD with an inexpensive Shimano compatible unit, road or MTB (8 or 9 speed) depending on how large a cassette I was looking for. I would then buy some inexpensive Microshift 9 speed brake/shifters, indexing would be perfect. And I've been very impressed with the function and value of Microshift shifters.
But like I said, I could completely be missing the boat re: what the OP is looking for.

For someone who has finger mobility issues, brifters or rapid fire type shifter would seem to be the best option since the lever 'returns' to the same position. Assuming a suitable position can be found which would work, it would limit the mobility needed. Friction shifters would seem to need more mobility range to work on most none downtube mounts.
Shimano's modern rapid fire shifters allow some adjustments on placement on the brake lever/mount.
Shimano shifters have quite a few option but the compatibility must be understood, something that the OP doesn't seem to be willing to learn.

BTW - I do understand the compatibility issues and have made these conversions before.

I asked a simple question about friction brifters for a reason. It is what I want to use for a couple of reasons that I didn't feel like writing a soliloquy about. Why? Because I expect to change the cassette from 9-speed and then likely to 12. That would require a new set of brifters, so it would be silly to spend a not insignificant amount of money on something that will be replaced.
BTW - I do understand the compatibility issues and have made these conversions before.

If you did mean ". . . to 9-speed . . . ", I'd just get a set of these; currently 65 dollars on Amazon. (FWIW, I got sick of trying to baby along a gummed-up set of 10-speed Ultegra brake/shifters and replaced them with a Micronew set. Much simpler and more positive shifting mechanism. Unless the louder click from gear to gear would bother you, I highly recommend them.)

Not quite sure what "expect to change the cassette from 9-speed and then likely to 12" means. If you meant ". . . to 9-speed . . . ," then see below. If you meant something else (I.e., "from 9-speed to 10-speed and then . . . "), there's likely a cheap Micronew brake/shifter set that would work.
