It was Avro 694 Lincoln with Napier Nomad II in its nose too. It served as a test-bed (so as Yak-42E LL).

I will peruse the links you are giving me.
I'm just thinking to make a short separate list of such racers which are hybrid machines though sporting contra-props....If I have time.... because now I'm working on "push/pull aircrafts"
besides I'm also planning to work on coaxial choppers (which also have contra-rotating rotors)
As you can see I'm putting too many irons in the fire.....
All the best

Whoops, I nearly goofed here .. getting confused between Spiteful Seafang. Seafang with contraprops - yes, but did the Spiteful (the F15) with the Griffon 89, which was used in the Seafang, also have contras? A picture would clinch it, for sure.

Photo from Alec Lumsden, British Piston Aero-Engines and their Aircraft, p. 172.
Nomad II was a piston engine.
Spiteful, concerning Robert Humphreys The Supermarine Spitfire, Part 2: Griffon-Powered, was only one plane F Mk 16. This was a basically F Mk 14 (RB518 ) with mounted Griffon 121 and six-blade contra-rotating Rotol prop. It was the end final state, because at first F Mk 16 had the Griffon 101 and five-blade Rotol prop.
And... the yet one small to explaining. On two photoes Airspeed Courier with the engine Napier Rapier IV is apparently - for my old eyes - two propellers. But nobody hereof does not write. Other photos show the plane on the fly, so with difficulty to say, how much it is blades.
The turbine's with the main assignment was to drive a compressor. Only relative small part of surplus power from turbine was given to propeller.2) the Napier Nomad engine was a supercharged diesel piston engine incorporating a turboprop
Thanks to recommendation from this site I have now Price's "The Spitfire Story" on the shelf. Excellent publication, too. Image inserted here from page 238 is self explanatory - I don't think I saw the MK 24 listed, Carson - although there was evidently only the one example, as the caption suggests.
The Lumsden book looks pretty tempting too, by the way!

Article here mentions the Spiteful XV. Also, as in the article, the XVI had a Griffon 101, not 121 and a single 5-bladed propellor. Seems the Seafang prototype was converted from the one XV built.

Books at home so no photo of the XV yet.
Carson, You can also add the Avro Lancaster to the list, here is Lancaster TW911 being used as a testebed for the Armstrong Siddeley Python in 1949.
I have another for you, the Fairey Firefly IV, a one off demonstrator that proved the benefit of comntra props to naval aircraft and was offered as an option for future sale but never taken up. the caption for the photo is below the other text, which does not relate to the picture.
