I do have a theory on the "A" & "B", one is yellow gold and one is white gold like the one shown on the first page of comments.
"A" = White/Silver 2 tone dial & Gold case
"B" = Black Dial & White Gold case?
The Black dial has a L8 21J 10BP movement and a L9 stamped case.
The 1961 Bulova Model price lists includes the following Princeton variants. The lists are not complete, but still are a good gage of what was available at time of list publication.
I bet there are some patterns in the unique Bulova model numbers. e.g. There may be a pattern with last digit in model number being associated with attributes like case gold color. I'm thinking they didn't randomly assign these model numbers, but w/ Bulova .....it wouldn't surprise me.

If you want to add your watch to the database, that would be great. Then we would have another white gold/black dial example. See: add your antique or vintage Bulova watch
I thought we had and FAQ on how to add pictures, but I can't find it now.... The add a watch page has some instructions. Hopefully someone will remember where the help/tutorial/instructions page for adding pictures is located.
