I agree that the asking price is a concours price for a Cab B. I'm not sure what it would be worth. There are so few Cab. B's around that sale data is scarce. I'd say that a rough rule of thumb is that a Cab B may be 2/3 the price of a Cab. A The owner did some remedial bodywork and paint after I saw the car so maybe those issues have been taken care of. We had the car in 2004, so my memory of it is not fresh. I just reviewed a few of my photos and it didn't appear that it had a detailed chassis, body off restoration
You are right that the white wheel should have a white emblem, I wasn't thinking of that. There were a few different versions of the enameled emblem, and the early ones did have a smaller star as in your photo. Since this star does not have the indicator light in it like the post 50 170 V & S, I would say that it is an earlier 170 V which had the directional switch with built-in light on the dash. I have one of these that came off my 38, which had an incorrect 3 spoke wheel when I got it. I would hazard a guess that all the 220 centers had a large star. I haven't made a survey, but of all the 220's I've seen, I think I would have noticed the small star on them.
