Hi there.
I bought an old second hand bike which was a total mess with no value except that it had attached this C-record rear derailleur.
Itīs quite a bit damaged, but it seems to be an early model 1st gen, the ones with the solid cage and engraved logo..
Inside the parallelogram there is a number 20 and a 4.
Iīve see some other ones with a 21 and a 84, so, I am assuming mine is from 1984 because of the 4? But, the 20 looks like it could be an earlier alpha model??
As you see, itīs quite scratched, with some bites and the upper body bush (stop plate) is a little bit damaged.
Just as it is, how much could I ask for it?
Would it be worth dismantleing it, and try to polish and restore the scratches? I guess the anodized finish would disapear.. and it could be worst..
Thank you!
