I do not know of a comprehensive list of 13ZN references, apart from Longines' archive. The list is undoubtedly, very long.
On Orologi & Passioni, a list of 30CH references was started a while back. Given that fewer references exist and numbers generally appear on case-backs, this list would be much easier to complete.
Regarding your 13ZN list above, the five digit numbers are order numbers, not reference numbers. Additionally, four digit numbers that appear on case-backs in the 1930's and early 1940's are also order numbers and not reference numbers. These 4 digit numbers are found on many early tre tacches (time-only) and mushroom pusher 13ZN's. As far as I know, 4270 is the reference number for mushroom pusher 13ZN's, though there may be others.
