Identification please

[one11]

When the Silhouette Challenge thread was active I occasionally posted a genuine unknown and always got a result. So can anyone help identify this 1930s twin engined transport ? The source was one of the thousands of photographs published by Real Photographs Ltd, initially of Liverpool and later Southport, between the late 30s and the 1950s. All were untitled but described in a sales list. If anyone has any of these then the list no is 2396. Thanks in advance

Thanks to that rather odd shaped front cabin door and the three adjacent cabin windows, I'd hazard an educated guess at a Blackburn C.A.15C Biplane

And let me confirm your educated guess, Sir. Blackburn CA 15C it most certainly is!

Thanks to both . Aviation History & Nostalgia thread can always be relied on in these cases
