Spanish Utility Model 114,146

This is an interesting Spanish Utility model - a kind of patent-lite. It dates from 1965 and appears to describe the p-pivot of a derailleur with the pulley cage from a Zeus Gran Sport, but with a pressed steel p-knuckle.

I have an Alfa 65? with this design of p-knuckle, but it has a later, offset pulley cage.
