Hi Brian, yes it is definitely Pennfield Ridge, No. 34 OTU.
Course No.9 A/Gs 23/3/1943.
When l was researching and looking through various websites l came across a photo of Trainee Pilots....and l thought, there is something about the picture that is familiar.......it was the same background as in my picture. The site was the Pennfield Parish Military History Society....go to photos on there and have a look, amazing. Some of our A/Gs ended up crewing with some of these pilots so it made identification easier.
I also have a photo taken at Mont-Joli but without the names unfortunately and its also not very clear. Will try to attach here .......my Uncle is 3rd from right front row. Maybe Sgt Exon is on there too. There are certainly some resemblances!! WONT UPLOAD, WILL FIND YOU THE LINK AND REPOST
Best regards.......Steve.
