Hello:

I am looking for the 21 Squadron ORBs for September of 1943. A couple of requests to the National Archives have yielded this response:

"Unfortunately, despite our best efforts, we have been unable to locate the requested material within the specified document."

Can anyone here help me?

Also:

My Dad was a WAG and flew with this squadron from May to September of '43 before moving to heavy bombers. Is there any way to find out whatever happened to his crew mates? Perhaps their service numbers or their hometowns? Anything.
All I have is their names:

Pilot: Sgt. E. BRISTOW
Nav?: Sgt. H. McLEOD
Gun?: Sgt. B. MOSS

Any help would be appreciated.
Thanks.
