Just picked this one up; it's a front loader and at this point I'm not comfortable attempting to open it. Yellow gold plated case is dated L8. I am pretty confident this is a Beau Brummell variant previously unseen/unknown. The case and diamond configuration is the same as the "QQ" , "RR" (yellow) and the "SS" (white), but the face is different. Rather than tiny indents and raised plugs around the perimeter, this one is a "pizza dial" with gold lines on the cream colored dial.
This was one of those watches that made me say "wow", when I open the box up. Classic 1950's understated elegance and in excellent presumed unrestored original condition, a few light crystal marks - keeping time.

1958 Beau Brummel "A"
per the 1958/59 Bulova Line Book
Wow, Kathy...that didn't take you very long. Nice ad find! I looked for hours to no avail. I may have only gone as far as 1959, I don't recall. I researched before it was in hand.
Edit: Off site ad per Kathy - she added it to the short ads. Nice - confirms 2 variants with this face in white and yellow. White listed first, so it would seem white is the first alphabetical letter variant if we ever figure what the letters are for this model.
I find two BB variants at $115 and 21 jewels that I have not been able to verify, the V (30817, white gold) and the W (30818, yellow gold). This could be one of those, but I don't know the difference with these $115 and the other ad for $89.50, maybe the higher is solid gold.
This case should have a proper notch located either near 6 (most likely) or 12 where the bezel meets the case. Gently insert a case tool to pry the bezel upwards and it should separate giving access to the movement. Be careful not to apply too much force inward with the tool, as it may separate the bezel as intented but slide in too far and hit the dial. I see where there are signs of case damage on the sides as a result of attempts to pry the bezel off there.
Beau Brummell, unsure of variant.
