This really does make sense after viewing this 2 pictures Rolexdoc. Please forgive me any of my dumb questions or thoughts that I may have made on this forum in the past, unfortunately I act annoying like Columbo with too many questions. Yet Rolex Doc really does make a whole lot of sence I must admit. The two sisters being 2497 and 2438-1 and the 4 brothers being 3448 in yellow and white gold, and 3450 being in 1st series red dot, and 2nd series roman numerals. That clearly does put in place the pieces of the puzzle in this part of Patek Philippe Vintage Watches.
