I suspect some will recognise this quite quickly.
G'day Kitbag. Unfortunately I'm not one of the 'some'.
No idea really. First thought was the very finny end of the XF-85. But no. Then I tried to work out the fin shape...
I can't figure out some of the detail at the bottom and at left of the photo. Now I'm thinking that the exhaust is not directly under the fin?
Just had a look at What Cockpit. Anything to do with the YB-49?
