I have had my eye out for this one in rose gold with the pink dial in working order but it hasn't come along. This is the first one I have seen in white with the slate black dial and fell in love with it. I think it is the "Q".
It is 14k solid white gold with a 21 jewel working movement.
Comparison shot with other HE models. And an ad that says which color is which variant.

Nice group shot and ad find!
Wow, another real beauty. I can see why you fell in love with it. It looks pretty minty.
1947 Her Excellency "Q" looks like a match to me.
