Anticorodal silver spokes : very first Montecarlo steering wheel. about 64-65. The anticordal finishing is standard ( as you can see on Momo catalog)
Anticorodal Black spokes: 66-67. Very rare in this finishing .
Here you are the presentation page of the original (NOS) 1968 catalog ( thanks Mr. Moretti...). you can read how Anticorodal is light and strong.

it's Italian... everybody knows Dante's language, correct??!!:D
and.... from Italian Wikipedia :
"Anticorodal brand name for aluminum alloys 6000 series: the main alloying elements
are silicon and magnesium. These alloys by heat treatment after heat treatment
develop intermediate mechanical properties in general lower than those of alloys
2000 and 7000 series.
They have good formability, machinability, weldability and machinability. They are used for
architectural applications, motorcycle and mountain bike frames, welded structures in general.
This system is the main class of alloys for the spare hot-worked and for those
derived from fusion. They can combine several favorable characteristics: good resistance
mechanical, relatively low sensitivity to hardening, good resistance to corrosion.
This is especially true for precipitation hardening of the compound Mg2Si. To obtain products
Normally this alloy extruded Mg and Si are maintained below 1, 5% by weight. The
Silicon, finally, increases the fluidity of the melt and reduces the coefficient of expansion, as already
also called the Al-Si alloys, also increases the resistance to intergranular corrosion
typical of this alloy."
