What’s worth more, the cage or the entire thing??
 

Just found this.
a friends junk drawer. Just gave it to me.

cage reminds me of some sunglasses Elvis wore

I'm not seeing value there. Its pretty beat up, and it wasn't special. I will sometimes keep derailleurs like this in my parts drawer, where I might use the cable fixing bolt, jockey wheels, or whatever.

I was under the impression these were desirable for the extra long cage, which can also fit a campy NR and / or SR rear derailleur.

this would allow rear cogs bigger than 23.

but, I’m mistaken on an hourly basis.

...it has some value as a workable alternative for a long cage rear derailleur that works well, that can be used on Simplex dropouts, like all the stuff people need/want to replace on French bikes.
If you flip it over, I think you'll find that it's constructed just like a Shimano Crane and Titlist of that same era, with a little clip with stops on it, to grab the edges of the dropout.

I don't think the Tourney ones have reached the same prices as the Crane ones yet, and they are less polished in terms of fit and finish. But they work better than a lot of other rear derailleurs in this application.

It's pretty easy to remove the claw hanger, but don't screw up the special washer with the stops on it thingy when you do so. If you lose the tension on the top pivot spring, they don't work well any more. You need to remove the nut first, if it's present, then carefully twist off the claw thingy, holding the mounting bolt in place with a hex wrench in a vise. Once that's off, it's easily mounted to a Simplex dropout if you thread it with a 10mm tap of the correct pitch (fine).

Pretty chewed up but a little elbow grease can work wonders.

No offense intended but that banged up rear derailleur is not worth much for restoration purposes. For functional purposes, it is just fine. Put another way, if I were in the market, I would not be interested in buying the derailleur. Again, no offense intended but the piece is neither rare or valuable, in my opinion. That said...

When I first go into vintage road bicycles, I frequently over valued just about anything that came my way, Now, years and thousands of components later, I have become a lot more selective when something comes my way.

Probably the highest reuse is to add a long cage to a short cage mech.
the parallelogram links are steel, work fine but not lightweight.

For those with stock campy derailleurs, these (the cages) are nice because you can use a freewheel other than a corncob.

Already through it in the metal scrap bin.

Thought someone was looking for one. No big deal.

Wow. It does not belong in the scrap metal bin. Why not post it as free plus shipping instead? It is a decent unit, and if not damaged might be the answer for someone's daily rider.

Its a co-op. sliding scale. Free if you can't afford. and there are literaly 1000's of old derailleurs to choose from.

Come and grab a barrel.

I asked if it was worth anything, Never heard it was.

Still there if you want to come by and pull it out of the bin.

Meanwhile, I'll be up front building bikes for those who can't afford one.

Good day sir.

Your original post said "Just found this. a friends junk drawer. Just gave it to me." Now you say its at a co-op with thousands (!) of old derailleurs -- that's apparently fine with volunteers throwing perfectly good working ones away.

You seem intent on trolling. Not sure why. :(

Good condition vintage rear derailleurs fall into the catagory of "gold" for those who pan through the parts bins at the co-op. Go through a whole bin of old co-op derailleurs and you'll be lucky to find 3 that are complete and not bent. And the chances are that you won't find 1 you actually want for a project.
