I must admit that I’m not 100% convinced that it’s from a Br.831, unless from a related prototype, even the one shown in the picture seems to have straighter cockpit framing around the windscreens area and possibly a solid panel in the centre cockpit roof postion.
The cockpit shown is completely clear and seems to have a distinctive steady curve throughout its profile, the annoying thing is that it seems quite familiar to me!

Looking at the cockpit framework I would say it’s is an Alouette III, but mated to a IIs rear structure, is there such a thing as an Alouette II.V?!
Alouette III is my final answer!

It was, that was partly the reason it didn’t see proper service.
The Martin B-57A was a licenced built E.E. Canberra bomber, which itself started out with a tandem two seat design cockpit (all be it with the bowl canopy that it retained in production bomber and PR variants), however due to radar bombing kit not being available it became a three seater with the pilot under the bowl canopy and the nav/bomb aimer sat side by side behind him.
The B-57 essentialy was a low level interdictor (before the RAF thought of it) and only required one nav who was retained in the aft stb’d position.
The B-57B introduced the excellent tandem seat layout under the large clear canopy, something that E.E. and the RAF should have done while drawing up the Canberra B.(I).8.

Shame that there aren’t more Martin designs about really, the Marlin is my favourite flying boat.

Agree with that Ross, I think the AHB say as such themselves aswel, they are ultimately the keeper of original records of the service, primarily for the services’ use and shouldn’t be regarded as first contact.
However my point (and I suspect Wellingtons’, Andys’) is that there does seem to have been changes in the response to requests in information just recently.

Looks like a Breguet Br891 Mars cockpit to me, but with some small windows added under the main glazing.

Unfortunately there was only one in the static park with non actually flying as there had been a crash or some technical problem which had grounded the entire fleet.

The other thing I do recall was the size of the beefburgers…. Man, was it huge!! The Americans never seem to do ‘small’ do they… Yum yum!!

Ah, wondered why there wasn’t an SR-71 flying at the show, agree about the burgers, they were the two reasons why I enjoyed the Air Fetes, 1991 was my last.

My last picture of an SR-71 at a Mildenhall Air Fete was taken in May 1989, in the static park. Seem to remember one at that years RIAT Fairford show as well.

No Andy, and I must admit I haven’t pressed them for a reason – yet.
I’m not sure it’s a case of jobs worths as such, as everyone I have spoken to have been very helpful, it seems to me that a new regulation of law has crept in recently (though that is only my impression) which seems to umprella official service records.
I don’t know if this has come about because of one case or what.

One reply I had was that I could only view a percentage of records, and even then that would be at the discretion of the assistant as to what I could view, and then as to what I could copy.

Interstingly I haven’t heard the same thing from TNA, but possibly because I’ve not asked for the same info.

I agree entirely with your comments about this effecting future publications.
