Hi Jerry,
I am keen to know where you heard about the different steering wheels. I have an early S1 460047 - May 1967 (wrong wheel when I got it), and one of the earliest 47 - chassis 47-GT-3 built late 1966.
I watch Serge Sleurs video and the early S1 wheel apparently has large holes. It would be nice to get confirmation from a few more early cars.
The wheel of the 47 (see below) looks the same as the Europa wheels, but it is likely NOT to be the original.
Interesting stuff!
