NoDeCo bezels from the 1960's - Dive tables question

[Flying Doctor]

This pic should show you where I'm at.

The SUB 300 and 300T Metric bezels are the same. The 300T Imperial is US Navy. The 300 Imperial bezel is the 300 Metric numbers with meters to feet and a bit of rounding.

If the 300 had used the US Navy tables then the 300 Imperial would be the same as the 300T. It isn't, so that's why I am doubtful that the original 300 bezel was based on the US Navy tables.

Little bit more on the 1955 edition

The 1955 edition, published by Arthaud, of the original 1949 book by Tailliez, Cousteau, Alinat, Devilla, and Dumas, representing GROUPE D ETUDES ET DE RECHERCHES SOUS-MARIN (GERS). The first book published on diving with the Aqualung by the first military unit to be formed around the Aqualung. The text is French. The book is authored by Cousteau and the GERS team and presented by the French MARINE NATIONALE.

That's precisely the book I'm trying to find on my bookshelf. Sorry too say, as it's been years since I had any chance to put some order in that mess, I'll need some more time. Please don't laugh. Maintaining any semblance of order in a 2000+ collection of assorted books, isn't any kind of pic nick, believe you me ! Anyway, if I ever get my hands on it, I'll post a picture of the darn dive table.
