Looking for photos of Coastal Command Wellingtons from 407 and 415 Sqn. Codes for 407 Sqn should be C1 and 415 should be NH, but I have not been able to confirm this.
closest thing I have is this pic from the 1982 415 calendar May caption reads
Vickers Armstong Wellington MK XIII "Saw sub sank same" Bay of Biscay 2 Aug 43.
