I am hoping someone can help me decipher some code found in a WW2 Application Book for Royal Navy Good Conduct and Long Service Medals.
The person in question has 'a/ch AA' listed under 'rating or ranking'. I am assuming the latter means 'Air Arm' but what does 'a/ch' stand for?
Under date received (which is 26 June 1950) there is also a code which looks like 'WOP' or 'OP'. The rest of the people in the list mostly just have a 'P' in this column next to their name.
Finally, the person's official rating is L/FX75949. I'd like to know whether the 'L' means anything specifically?
Thanks very much in advance for any light you can shed.
