We've been through this before. When Hunting was being absorbed into BAC it was decided to rework the 107 around the RR Spey engine and my understanding of what I remember being told by Heinz Vogel was that 111 was the next available Hunting type number.
Before all that was Airco which consisted of de Havilland, Hunting and Fairey and the original Trident was an Airco project, albeit with a DH type number.

Certificated by UK and subsequently EASA as "BAC One Eleven" and by FAA as "BAC 1-11".

Take your pick.

That link would have saved me some typing! Your list does not mention the Putnam book, but I guess it's your source too?

I concur with "VC15" for the Super VC10 as this is how the BA ones announced their aircraft type to LHR Approach.

I used the Putnam and a few other books and magazines. I haven't kept track of the precise sources unfortunately, so if there are differences, I would need to dig through a couple of publications to find the why.
Edit: 'Stuck on the Drawing Board' has some notes about some of Vickers' unfinished projects as well. The only major difference between the list on my site and the one in Andrews & Morgan's Putnam book is the VC9. I have seen a few references to the Vanguard that called it a VC9 (which may be based on its ICAO type designator, but I can't confirm that) and it fits in the timeline... That's my reasoning. ;)

VC10
 

Would love to have flown in one as a passenger and it would be great to see them still flying but I don't think the economics cut the mustard.
Still have a BOAC Junior Jet Club logbook which I was given whilst travelling as a boy on a BOAC Comet 4 (1964 and in First Class) in which there was a promotional leaflet on the upcoming introduction of the VC10.

Yes it would be great for people to experience what it was like to fly in those aircraft but getting parts etc. would be an economic nightmare.
Have to give it to the British aircraft industry credit for what they achieved in the 1950's and 1960's. One example being the introduction of Autoland capabilities in the Tridents.
I certainly dig log many miles as a passenger in the Viscounts as a boy.
Just feel grateful to have flown in Tridents, BAC1-11, Sunderland/Sandringham flying boats,BAE146 and Concorde.
Also the Caravelle10R although manufactured in France had a Dehavilland Comet cockpit.

Must admit that I miss the sound of those aircraft when they took off.
..

IIRC, on 101 Sqn we used VC10 on hand written flight plans for the Mk2s (Standards) and VC15 for the Mk3s and 4s (Supers).

Nice empennage, Lol...I don't believe it but the match is quite uncanny!

I spent a couple of years ground handling Merchantmen and we always used VC9 as the type code on our records.

Part of the reason I wanted to fly was hearing just how loud a jet can be. I could hear the undiluted roar from those engines because I lived about 1/2 a mile away from KLGA. Naturally, I wanted to control all of that power.
