Rutan may have been inspired by this, perhaps?

Rutan's first unusual design was the Vari-Viggen, a delta-wing canard like the Swedish fast jet from SAAB that inspired it. Canards have been around since the American Wright brothers. The swept-wing canard was included in British patent No 26441 by British pioneer JW Dunne and granted in 1910, and first appeared in the flesh (to my knowledge) in the Italian Ambrosini SS.4 of 1939. The German WWII work was widely circulated during the late 1940s, but had been assimilated and all but forgotten by the time Rutan's generation came along. SAAB developed the idea of close-coupling the canard to the wing, in order to obtain a positive interaction between them. None of the projects documented by Frost do this.
The B&V Ae 607 was a single German drawing of a canard delta (and perhaps the very first design) foreshadowing the SAAB conception. Here's an image of a clearer re-drawing from the linked discussion.

Did SAAB's inspiration originate in this German drawing? It was so utterly obscure for so many years that even Frost did not record it. It only came to people's notice after the SAAB/Rutan revolution. So the link is extremely unlikely.

A mistery project to me, published in 1941, Flugsport magazine, heft 26-8. A fighter, with a DB 601. Maybe stemmed from a TH rather than an aircraft company.

that is the Skoda-Kauba V-7
 
Henschel P.75

Designed in 1941 to replace the Messerschmitt Bf 110 applying the ‘canard’ formula,

the most advanced at that time. The canard was also used for the S.A.I. S.S.4 fighter

in Italy, for the Kyushu J7W1 Shinden in Japan, and for the Curtis XP.55 Ascender and

Lockheed L-133 in USA.

With this new configuration the designers tried to elude the problem of compressibility buffeting by installing the wing behind the center of gravity.

The system had the advantages of allowing the installation of the armament in the

nose and improving the pilot’s visibility.

The downside was that the pusher configuration required the installation of an

ejector seat or a detaching system for the propeller blades, to abandon the airplane

during flights in an emergency.

The P. 75 was originally designed around the DB 610 power plant. However, due

to the bad results rendered by this engine during its service career with the He 177

bomber, it was necessary to adapt the project to the new DB 613 (of bigger size) in 1942.

This engine was formed by two coupled DB 603 driving two contra-rotating propellers

via an extension shaft.

Technical Data

Type: Canard-pusher heavy fighter.

Phase: Wind tunnel model.

Undercarriage: Tricycle type, hydraulically retractable.

Engine: One Daimler Benz DB 613 A/B liquid-cooled, 24 cylinders coupled engine with

3500 hp and contra-rotating propellers of 3.2 m of diameter.

Fuel tanks: Two in the wings and one in the fuselage behind the pilot.

Armament: Four 30 mm Mk 108 cannon in the nose.

Equipment: Pressurized cockpit, ejector seat.

Wingspan: 11.3 m.

Length: 12.2 m.

Height: 3.96 m.

Wing area: 28.4 sq. m.

Max. weight: 7,500 kg.

Max. speed: 790 km/h at 7,000 m.

Service ceiling 12,000 m.
