Can anyone identify this aircraft??
If you want the full history of the Mew Gull try and find a copy of 'The Flight of the Mew Gull' by Alex Henshaw. Excellent book which gives its complete development history by Henshaw and his record breaking flight to Cape Town and back.
I must admit when I first looked at the three view I thought it was a Dewoitine WWII fighter job..... but the Gull does seem about right.
