Thanks Clint
The Halberstadt B-types I have seen all have the D-fighter types fins.
Only one differ and that was a pre-war model.
I don't have the Aeronaut book....yet.
I am notoriously lousy in identifying German indifferent two-seaters, so I pass with regard to your comment of type....
, but it is puzzling isn't it with those Bestell numbers? The main number is repeated in large digits as well on the fuselage.
Must have something to do with their training capacity, and who knows, probably outside the normal channels.
Very intriguing.
Cheers
