Simplex Juy 61 racing rear derailleur 1961

Very rare rear derailleur from 1961/1962

used, in technically perfect condition and

high spring tension

Very rare rear derailleur from 1961 - 1962, made in France.
Unfortunately, the previous owner meant it more than well when cleaning and the Simplex logo engraved on the riveted vignette
polished so well,

that the logo can only be recognized if you look closely.
The rear derailleur has no defects from a technical point of view, the spring tension is still very good and is all in all for its age
in a very good condition.
