I've bought a number of rear derailleurs so I can finish some long overdue bike projects and I've got two that I'm not sure what they are. I put them in a box marked "8-speed" but no other descriptors.












I like it when derailleurs say "Nuovo Record" or Super Record or Record titanium 9-speed on them but these two are no help. Are they Chorus? Athena? Croce d'Aune? C-Record? Daytona?

On another topic, I'm thinking it might be crazy to use these tires on my Paramount commuter bike project. I've got four of them.
