RAF CRANWELL
APPRENTICE ENTRY NUMBERS

Whilst most training schools had simple number sequences for Entries, two more puzzling systems were adopted for Apprentices at RAF Cranwell. Both systems were intended to indicate the TRAINING COMPLETION YEAR and COMPLETION MONTH plus CLASS.

During the period 1926 to 1936

During this period they took the form YEAR figure + MONTH letter + CLASS figure, with only "J" for June and "D" for December used for the MONTH.

Thus 9D1 meant Class 1 Passing Out in December 1929. Trades in training during this period were Wireless Operator Mechanics (WOM's), Electricians and Instrument Makers. Classes 1 and 2 were normally Wireless Operator Mechanics, Class 3 Instrument Makers (IM) and Class 5 Electricians but this was not always the case.

During the period 1933 to 1955

During this period they took the form YEAR figure + TRADE letter + MONTH number + CLASS letter.

Initially the trade letter J stood for Instrument Makers while M stood for Wireless Operator Mechanic (WOM) or Wireless Electrical Mechanic (WEM).

Thus 6J12 meant Instrument Makers (J) passing out in December (12th month) 1936, while 6M12 meant a WOM or WEM (M) passing out in December (12th month) 1936. Adding a Class letter would give say 6J12D and 6M12B.

During the 1940's four Entries of Polish Apprentices were trained as Radio Mechanics. They were known respectively as the 7P9, 7P11, 8P3 and 8P9 Entries.

The limitations, and confusions over a period of time of this system, can be seen by considering say the 0M1 Entry which applies to a 1940 Entry (the 36th) and also a 1950 Entry (the 55th). About 1948 this numbering format was officially discontinued in favour of the simple Halton sequential numbering sequence, but sometimes Entries still called themselves by the Cranwell notation.

Apprentices in peacetime were for 3 years, but during the war, to bring urgently needed skilled tradesmen into productive service quicker, this was reduced to between 2 and 2 years.
