Hi,

Can I ask about drawing to Blackburn M5/28 Torpedo Ship Plane ?.
 
Contact BAe Systems Heritage and request a copy of drawing ME1251 (archive reference B3883). This is a side view and appears to be the only drawing they hold for this project.
 
Thank you my dear Schneiderman,

and can I ask about Blackburn F.34/35 two-seat fighter ?.
 
The British Aircraft Specifications File by K J Meekcoms and E B Morgan, Air Britain 1994, describes a Blackburn design which may have been to specification F.34/35 for
"a two-seat turret fighter, based on the Skua and powered by a Merlin C. Drawings dated 17/4/35 depict a machine differing only in detail from the Roc. Span 44 ft, length 30 ft 4.5 in, height 10 ft 6 in."
Again, may have been.

Imagine a Blackburn Roc with a R-R Merlin C instead of a Bristol Perseus radial.

Gloster worked on a turret fighter of their own, with fixed armament in the nose, to F.34/35 - that ended when the Boulton-Paul Defiant was built to F.9/35. I presume that was also the end for the 'Merlin-Roc'.
Specification F.34/35 was replaced by F.9/37, which led to the Gloster G.39.
 
It might not have been catalogued under F.34/35.
Searching for Blackburn Roc in the Archive might help. Then again, maybe not.

Of course. But then broadening the search using two seat,twin-engine, fighter, turret and so on also turns up nothing relevant

That has been copied, incorrectly, from Jackson's Blackburn Aircraft since 1909. There, it says
"a two-seat turret fighter to Specification A.39/34, based on the Skua and powered by ......... Merlin C........ drawings dated 17/4/35......... depict a machine differing only in detail from the Roc.............. Span 44 ft, length 30 ft 4.5 in, height 10 ft 6 in." It is also illustrated in that book
 
Oh, I should have added that A.39/34 was for an Army Cooperation aircraft (Lysander) so Jackson was wrong, but a 3-view of the project is in the Putnam book.

@Schneiderman Well done! I have a revised edition of Jackson's book, I simply took the Specifications File because it offered an easier search for F.34/35.

This thread has be very useful in pointing out the possible problems in the Putnam and archive. I have a nice helpful contact in the BAe Systems archive and we will look into it and let you know what we find.

Which Jackson described as "...which differed only in detail from the Roc."..........................erm, apart from the wings,...... oh, and the tailplane, fin & rudder, ......um, also the fuselage and don't forget the cockpit too. Mere details, I guess.
 
The Roc's folding wings, the retractable fairings in front of and behind the turret, all notably absent from the older 3-view.
Roc 3-view from Jackson.

OK, the drawings in the BAe Systems archive have been checked and the project was indeed designed to meet A.39/34

Judging by the louvers, it’s’ radiators are installed in the wing root fairings/fillets.
