I'm sure you have access to lots more advertisements than I do, so I'll trust your judgements. I was mearly going by the 2 examples in the database for 57. a Surfmaster and a Surfmaster A of which a panel member at that time showed an ad for a Model 23 U that looked the the one called the A.
I probably made a poor assumption thinking the round one was the Surfmaster and the square one was an A.
The only shaded dial I saw going thru the ads again was for a square Ambassador.
