Forms, Lettered
Lettered forms seem to have been created by a formation (HQ, Group, or Wing) for internal use.
A typed master was circulated to all concerned then subsequent use was by teleprinter or message form.
A group of text relating to a particular space in the master form was given a line letter e.g. A, B, C etc. and listed on the teleprinter/message form. Where no text was entered a Nil was recorded against the line letter.
Bomber Groups seem to have used the same lettered forms
Form A - Command Operational Order
Form B - Group Operational Order
Form D - Unit Operational Report
Form E - Group Operational Report
Form F - Report of enemy attack on aerodrome?
Form G - Return of Airframes and crews
Form J - Return of Group Operational Effort?
Form P - Propaganda
Form Y - Unit Operational Intel Debrief Report
Form Z - Group Operational Intel Debrief Report
Edit
Just to confuse things even further I have picked up references to Forms A, B, C, D, F, G, M, Q, R and S in Kings Regulations.
They are all in The Manual of Air Force Law AP803 and relate to Arrest and Custody (before Sentence), Disposal of prisoners etc.

So Letter series forms vary from Command to Command and Branch to Branch.
