Who would have thought that there would be so many different steering wheels!
The two spoke wheel with the offset spokes and the ridges that Jack shows above appears in a picture in a The Motor road test for a 1951 Slough Light 15. By 1953 the wheel with no offset and three steps has appeared :

This one was on a car advertised on eBay as 1953 and also appears on a car in Jon Pressnell’s book in a 1953 photo. Oddly this type also appears in another photo in JP’s book on a 1946 car. Whether this is the correct wheel for that car or a retro fit, I don’t know.
