The same seller recently sold a "1958" Ideor Asso:
He included the following text:
"I got this frame from the original owner. He said he bought it new in 1958." and "Bike originally came GS Derailleurs"
I think we can assume these are the parts that came from the Ideore. In reality, those derailleurs and shift levers are identical to those on my 1959 Legnano, 1960 Atala, 1961 Olmo, and I probably anything from about 1956(?) until the open "C" disappeared from the shift levers... (Hey Chuck Schmidt - what year was that?).
