Rules for civil / military registration from 1935 to 1938:

Civil registration:

OE-A.. / OE-D.. Sports aircraft
OE-L..  commercial aircraft
OE-P..  police aircraft
OE-S..  aircraft of a flying school


Military registration:

1935:

the three-letter registration decodes as follows:

first: 
        class A:   T without / M with radio equipment
        class B:   F    "    / N     "
second:
        K  .. cabin
third:
        Type of aircraft,
        i.e.: F / L .. Udet 'FL'amingo
              H / O .. 'HO'pfner
              M / E .. 'M'ott'E' (german for Moth)
        (there are no more examples in this book, but I think
         you can figure out more from the designations
         themselves.)

Another quite funny thing which appeared to me:

When you look at some registrations they follow the vocals AEIOU in second 
place: TAF TEF TIF TOF TUF for instance. AEIOU was a sequence used by the 
Monarchs of Austria and is often translated as 'Austria Est In Orbe Ultima' 
(Austria is the highest in the world, or something like that, latin was not 
my strongest side at school...) or in german 'Alles Erdreich Ist Oesterreich 
Untertan' which means the same as above. funny, isn't it ? but it becomes 
more clear when you know that the first commander (and the one who built it 
up in secrecy) of the austrian airforce after WWI was a decorated WWI pilot, 
Alexander Loehr.

More designations:

the service number is decoded as follows:

first digit:
        1 .. fighters
        2 .. reconnaissance
        3 .. bombers
        4 .. trainers of class A
        5 .. trainers of class B
        6 .. everything else
        9 .. gliders (was added later)

the other digits represent the serial number of the plane.

In 1936 the letter registrations changed their meaning:

first letter:

F .. class B aircraft
M .. fighters (dropped when the cockade was introduced later)
N .. reconnaissance ( dropped, used only for the Ju F13 )
T .. class A aircraft

R
H
I
V
X
Z
were reserved orally for future use with the Ministry
for trade and traffic (Aerial department).
