the following is what I personally subscribe to, keeping in mind that very few "official" documents are readily available among insufficient, potentially missing or other information just not surviving into present day. For example, the official government registration form or confirmation document granting the F.I.A. non-profit status (marking its birth), would be a great historic piece of paper to see if the FIA would see fit to establish a real digital archive beyond basic race and championship statistics, containing historically important documents, technical memorandums and (hopefully) missing or incomplete race event information.

Assessment of the general timeline and specific dates of events (if available), leading to the inception of the specific terms or words: F.I.A. - CSI (Commission Sportive Internationale), Formula A (B), Formula One

Regulations immediately leading up to 1946:

1938-1939

Formula, based on a sliding scale of weight in relation to capacity:

3-liter supercharged cars (minimum weight from 400 kg - 881.84 lb)

4.5-liter normally aspirated (minimum weight of 850 kg - 1873 lb).

Net weight to include tires, all oils, fuel (but not cooling water), tools and spare wheels.

Free choice of fuels, minimum race distance 500 km (312 mi).

Ratio of supercharged to unsupercharged engine was 1:1.5.

1940-1945

1946

Pre-war Formula specs (used until 1939 and still in effect) were annulled on February 28, 1946 at the first postwar AIACR meeting.

Cars from the 1939 3-liter supercharged era and voiturette formula.

No weight restrictions.

Minimum race distance of 300 km (186 mi) or minimum of three hours.

1949 (Formula A, B)

The same as for 1947/1948, free choice of fuels.

1950 (Formula One)

1946-Present: FIA /CSI formation, Formula A (B) (definition)

1947: Formula A cars (first appearance)

1948: Formula A regulations in effect

1949: Formula A regulations in effect

1950: Formula A officially renamed to Formula One, start of Drivers World Championship (first official use of the term "Formula One")

In my own daydreams, I like to think that there might be still a chance for a few odd documents to have survived the war, flood, fire or general neglect in various attics, cellars or other dark and dusty corners, from among local promoters, car clubs, event sponsors... maybe even from a 1934 hot dog & beer vendor... lol (I could use a few more circuit maps)

great points made here... hope my take on this is at least half-way there
