Hi Aaron,
@Huffy45
I'm not an expert on this, but there appears to be a B17 in 8th USAAF/ 1st Air Division / 1st Bomb Wing red tail markings, so either 91st, 381st or 398th Bomb Group. Also it dates the photo to after July 1944 when these markings were introduced.
381st Bomb Group B17's
The 91st operated from RAF Bassingbourn, Cambridgeshire, England.
The 381st operated from RAF Ridgewell, north west of Halstead, Essex, England.
The 398th operated from RAF Nuthampstead, straddling the border of Hertfordshire and Essex, England.
The house visible behind the Dodge Command Car may help tie it down better.
Or, of course, it could be visiting (-:
The signal caravan was originally built for the British and the remains of British 'Mickey Mouse' (ears) camouflage is still visible.
The controller is using an Aldis lamp and standing under a recycled aircraft nosecone, possibly from a B26 Marauder?
B26 Marauder
Best Regards,
Adrian
