So, I spent some time pouring over some books - and can't find anything exactly like that. The closest I could find was a very similar two spoked design found on a couple 1948-51 6C 2500 cabriolets (though not all of them seem to have the two 'open' spokes - some had thin solid spokes like in the picture below) Can't find any digital pics of the two open spokes - and I don't have a scanner handy to scan the pics from the books. One book is the Alfa Romeo Buyer's Guide, Second Edition by Joe Benson. Pic is on page 18. Problem is that these cars had a different looking dash - with lots of Bakelite or Ivory knobs and the center medallion on the steering wheel hub appeared to be a clear resin (again, like the pic below from a '51 car).
So P1Lizzy - what else can you tell us about the car in the photo?
A 1949 6C Freccia d'Oro - car has same center band running through the dashboard, so it appears to be same/similar model. The steering wheel is the more common 2 spoke bakelite or whatever material that I've seen on most every other car.
It's possible the steering wheel is not original to the car...
Robergel, a French company, made some steering wheels for Italian and French cars of the late 1940s - early 1950s, including Ferrari, Alfa Romeo, Fiat, Simca Sport, Delahaye, etc. This looks like it might be a Robergel steering wheel. They also made road wheels.
