Searching for a box with reference 10.00.1

[rufus75]

Dear all
first of all thanks to be admitted in this fantastic forum. i own a old rolex date bought in 1976. I own everything (warranty, the calendar etc...) but the box is broken. I have lost the cap of the box.
The box has a ref. code 10.00.1 and in the interned i have found different box caps (flat and multifaceted).
somebody can explain to me the which is the original one?

The cap of the box?
The top maybe?
If so the top if which box, Inner or outer?
