DD numbers in ORD records

[Erik-123]

Hello,


I read some ORD records and noted in the page entrence "Duty" in some cases a duty number like: DD801 or DD793.
They seem to be al diffrend. Is there a list of all these Duty numbers and what kind of duty it stands for?


Kind regards,

Erik

Hi Erik

Just checking - it isn't that the typist hasn't bothered following the page layout properly is it? Those look like a/c serial numbers rather than 'duties'.

Although similar numbers were allocated to actual aircraft, DD801 was not, and DD793 was a Hatfield-built Mosquito II, so this would sem not to be the answer. Interestingly DD804 was one the Firebrand prototypes. I think the anwser must be elsewhere.
