Maybe a needle in a haystack kind of question. But does anybody know what this rear derailleur hanger fits? It's been in the parts box for a couple years. I mostly work on vintage-ish road bike stuff so likely along those lines. Thank you.

We don't see many modern hangers like that in this subforum. But Google Lens can help with this sort of thing. It may be from Giant.

Looks like this one, which they say was used by "Airborne, Avanti, Bergamont, Breezer, Brisa, Centurion, Cinelli, Coluer, Corratec, Cube, DaBomb, Diamondback, Focus, Fuji, Go Sport, GT Bicycles, Hasa, Intec, Kalkhoff, KHS, KTM, Marin, Massi, Mongoose, Nakamura, Nirve, Orbea, Qbike, Raleigh, Saracen, Schwinn, Scrapper, Vario, Venzo, Viper, Wheeler, ..." (3 dots meaning more as well?)

I know practically nothing about this "dropouts.info" website other than they seem to sell lots of different style hangers, appears to be hundreds of them. Oh I see they say "1000+". In German, with prices listed in Euro. But of course you're not interested in buying one, this is just an informational database.
