I don't know about that... having a complete list with production variants can be interesting - especially given that production of the series was cut-off well before it was complete.

Does this mockup represent a totally different aircraft from the MB.500 T3 or is it a derivative of that 1938 trainer?

My dear Apophenia,

I think it was a derivative of it.

Here is a small Info about MB.164 & MB.165,which I thin they were a Projects ?;

The second was originally a grand raid version of the MB-160 but in the end, the designation MB-162 planned for this aircraft which made its first flight in the spring of 1940 was attributed to a bomber declination of the MB-160 and as the designation MB-163 designated a maritime reconnaissance version of the MB-162 (two prototypes) and that the designation MB-164 was reserved for a VIP transport version, it is the designation MB-165 that this aircraft received.

Two prototypes were ordered by the Air Force in December 1942 and delivered in May 1943 for six months of intensive testing. It was therefore in November 1943 that the Air Force decided to order 36 Bloch MB-165s, but Bloch being very busy with other aircraft, it was not until July 1944 that the first aircraft series are delivered, the entire order being fulfilled in September 1945.

Hesham: be careful... this is not real ! I know that blog author, Clausewitz. A nice fellow, not a hoaxer by any mean. But this is alternate history, not real. https://clausuchronia.wordpress.com/

That doesn't mean anything in that link is actual information, as opposed to fiction.

Bloch M.B.700



The Bloch M.B.700 was designed as an answer to the Programme technique A.23. This small interceptor differentiated from the Roussel in that it was built from wood. This fact made its mass production easier as it did not require strategic materials that could be used for the Dewoitine D.520 conventional fighter. Outwardly, it looked like an 83% scaled down version of the conventional fighter Bloch M.B.152. The main advantage of the M.B.700 reduced size was that while equipped with an engine with 75% the power of an M.B.152, it flew 80 kph faster, still carrying the same armament, and was a more difficult target in dog-fight.

In 1939, a prototype was built in the Blériot-Aéronautique of Suresnes, flying for the first time by mid-April 1940. During the flight tests made on 13 May, it reached a maximum speed of just 380 kph, instead of the expected 580 km/h. As a consequence, the Mercier engine cowling and clear canopy were modified, and external plates were installed in the main undercarriage.

The airplane was destroyed shortly afterwards by the German troops in Buc airfield. There was a plan for a shipboard variant named M.B. 720 with tail hook and the armament reduced to four MAC 1934 M 39 machine guns.



Technical Data



Engine: one 700 hp Gnôme-Rhône 14 M6 fourteen-cylinder, air-cooled radial engine driving a Gnôme Rhône variable-pitch airscrew. Armament: two 20 mm Hispano-Suiza H.S. 404 cannons and two 7.5 mm MAC 1934 M39 belt-feed machine guns mounted in the wings. Wingspan: 8.9 m, length: 7.34 m, height: 3.4 m, wing surface: 12.4 sq.m, maximum weight: 2,000 kg, maximum speed: 550 kph.

The Bloch MB.190,

the MB-190 touring tandem was built from 1936 in SNCASE
workshops in Berre. this copy was all metallic and planned with
a Renault 140 hp engine. A second copy, replica to the first, but
all in wood was simultaneously under construction at Courbevoie.
This second machine, equipped with a Gipsy 130 hp, flew in
June 1937. This cantilever monoplane with low wings, two-seater
in tanden had a sliding glass roof interior and dual control. Of
similar to the Miles or Percival planes, it was painted red
carmine. It seems that only the Courbevoie copy has flown.
