The C.24 built by de Havilland in 1931, using a Cierva rotor head coupled to the cabin of a de Havilland DH.80A Puss Moth, and driven by a 120hp Gipsy III engine.
I think the answer lies in the fact that the site that the R-1 drawing comes from is a fantasy one. Looks very like a kamov design to me.
True, but please notice that most photos on that page depict real-life aircraft. If you look at the picture file's name, it says "Cierva C.29" and that's exactly what it depicts.
I'm still wondering what the would-be "Cierva R1" is supposed to depict, though, if anything at all.

I totally agree, the fact that this site mixes fact and fiction has given me grief in the past when I've thought that I've found a new type. I didn't dimiss the R-1 right away, had to stop and think about it.

Found this interesting Cierva in my archives, but I can't identify it. Help?
It looks like it maybe an early type of Gyrodyne design. The kind of design that J.A.J Bennet was working on at Cierva just before the second world war, and later developed when he went to Fairey, but I've never seen anything like it before.

I stand corrected, it's not a Gyrodyne design. When enlarged you can see that the propellor is on the nose not a stub wing as I first thought. So I'm still none the wiser.
As I mentioned above, the Fairey Gyrodyne design originated in a proposal that Dr J.A.J.Bennett put forward for the Cierva Company to meet the specification S.22/38 for a naval rotary-wing spotter/reconnaissance aircraft.
The two images are from U.S patent 2317340 and show what is probably the basic layout of the Cierva C.41 design. They show subtle differences.
The model of the projected twin engined version of the Air Horse, the W.11T, first shown at Farnborough in 1949, still exists at the Helicopter Museum in Weston Super Mare.
What would appear to be the last projected Air Horse development, before Cierva stopped work. Of special interest is the folding rotor system, which implies a Naval application. Perhaps a potential competitor to Bristol's Type 191 or designed for on-board delivery.
The first image from U.S Patent 2503172, shows the version with Jet Reaction control. The system used by the W.9. (Compare with photo at start of this thread).
The second from U.S Patent 2440225, shows a version with a tailplane.
The third and fourth from U.S Patent 2613748, show a version with a curious fan arrangement.

Am I correct to assume that the Cierva-Shorts C.14 gyro was a flying boat type like the C.13 or was it a completely different project? I'm fact-checking against vague Google results.

Stéphane made it pretty clear in the designations topic that no details have survived to indicate exactly what the C.14, C.15, and C.16 projects actually were, so assuming any relation with Shorts or development around the C.13 is pure speculation that is likely to never be proven. Such as it is with designs forever lost to history.
