Birkett Air Service ltd

Hi everyone, research is still on going with Barton(Beds) airfield and I’m starting to look a little more into the later years.

I’m looking for information on Birkett Air Service ltd.

I have pulled the available information from the FlightArchive but would appreciate any extra that forum members may have read or remember… date would be 1938-1942. (29th ERFTS)

many thanks
Jenna
