Here is my small contribution to your superb post:
1/ 1675 " Mar Del Plata " from 1966:
2/ 6542 from 1958 with an unsual guarantee booklet ( earlier, but hey, who knows? )
3/ Bill's awesome 6542 from IV '57:
4/ My sweet 6610, from I / '57:
And a few others I will have to take in pictures, such as a Red Sub from 1972, the Triple 6 from 1981, and a 16550...
These Rolex Ephemeras are so complex, indeed!
Thanks for the effort, and for the very interesting post.
Best,
Nicolas
