A.I.D. Inspectors

[Richard Farrant]

Rich,

I would say that AID were only involved with Air Ministry contracts, which of course could have been running alongside Army ones and would have included all parts for spares as well.

The M over 74 has a Broad Arrow mark of the War Dept. above the M, and having seen this type of stamp on other vehicles would say that is the War Office inspectors stamp.

The AID stamp is a very small circle with letters/numbers within and needs a magnifiying glass to read, it is that small.

Something interesting on your photo that I have spotted, it is the letters "JLO" within an oval. Now I think your Norton was left behind in 1940, and so, must have been captured and used by the Germans. JLO is / was, a German engine manufacturer (air cooled stationary engines for generators, etc.) and at a guess they may have overhauled your engine during its service with the German army.
