D-8, R-7 and a big round O

These pictures are again from the Krul archive. Well, the O is the Danish cockade, of course (but it just fits for the headline). The labels were only the registrations or I think are wrong.

D-8 is a Blackburn Shark.
R-7 is a Bristol Bulldog I.
“O” is a Bristol Bulldog II, not a Hawker Danecock, as Krul says.

Please comment.
