I don't think the guns were fitted at the time the drawing is based. Howevewr, you are correct in that this is post Fokker /Constantinesco etc. interrupter gears , so that wasn't it's claim to fame.
Not a Nieuport.

GBZ The evolution of Nieuport to Gloster post-dated this aircraft's existence. It does have a sort of Folland look about it though doesn't it?
It's not a Folland design, incidentally.

The original intention was to fit the mystery aeroplane with a 200 h.p. Clerget 11E . As this engine was then only at a prototype stage (it was never a success in any event) the next scheme was apparently to fit a 160 h.p. Gnome Monosoupape 9Nc.
In the event the aircraft was eventually (under)powered by a Clerget 140 h.p. 9Bf.
Schemes existed to power developments of this aircraft by 250 and even 300h.p. twin row Clerget engines. These however, like the engines, didn't come to anything definitive.

Looking at the drawing there seem to be recognisable "bits" from different aircraft, especially from Sopwith ones. Is the mystery aircraft the Frankenstein's Monster created by Alcock from different Sopwith models - the Alcock Scout?
This really is a guess as I have never seen an illustration of it.

A very logical postulation!
The Alcock A.1 a.k.a. the Sopwith Mouse. It basically used the upper wings of a Pup the lower wings and forward fuselage modified from a Triplane and the tailplane of a Camel mounted on a new build rear fuselage and fin and rudder. The top wing was at eye level , thus improving the pilots overall field of view, particularly in the upper hemisphere.
As you can see in the drawing below it is not the aeroplane in question though.
Do look again at the mystery aircraft for its aerodynamic feature claim to fame.

Thanks for the illustration RETDPI. At least I know what it looks like now.
As for the challenge, possible aerodynamic features are; engine cowling, rounded wing tips, "I" struts, staggerwing and pilot placed behind the wings for a better c.g.
None of which helps me to identify the beast.

I've found a reference to an aircraft named the Courtois-Suffit Lescop CSL-1. Apparently one of the first to have slats on the lower wings. Could this be the innovation referred to? There's a suggestion of something like slats or slots on the lower wing on the 3 view

The aerodynamic devices first featured on this aeroplane are not mentioned in your list.
As a further clue this device is today found on a lot of high performance aircraft, for example many jet airliners.
The mystery aircraft was not British.

Puddinghead ,you have a most inappropriate moniker!
The device in question was not actually a slat or slot but a leading edge flap. These are visible on the lower wings in the drawing and could be hinged to effectively change the camber of the wing, primarily as an aid to lower approach and landing speeds. Unusually this device is also visible on the leading edge of the tailplane.
The mystery aircraft is indeed the C.S.L. 1
Designed by Roger Courtois-Suffit along with Capitaine Lescop the C.S.L.1 flew first in January 1918.
A very logical and well observed response, if I may say so.
Puddinghead you have control

Most kind, but accepted only if by "pipped at the post" you mean that I would not have got the answer in a month of Sundays. Great challenge, a new aircraft to find out about.

Absolutely correct
The 1948 NC 1071 was the first French multi-engined jet - designed as a carrier- borne trainer, it was to have been developed into a torpedo carrier. I'm not sure what became of the project - I found it in a 1949 reference book.
You have control RETPDI
PS You'll be pleased to know I find flying that other european multi-engined jet much more straightforward that posting images on PPrune.....

Thanks Puddinghead. There was a plethora of unusual designs immediately post WW2 from France and that was one of the more bizarre. One NC1071 prototype broke up in flight and it was discontinued - just as well I would have thought.
