Interesting theory, it did have a rigid(?) rotor.

Additional question - from engineering point of view - what is the advantage of such configuration?
Perhaps to balance the increasing lift of the advancing blade vs the decreasing lift of the retreating blade in cruising speed, with moderate blade pitch changes?

Do you happen to have a source for the HP.122 as a VTOL turboprop?

What concerns me about the SB.8 is that it was (apparently) pitched at HR.144 and all the other bidders look like parrot cages on skids. The SB.8 looks far too modern (and complex) for that spec. More Robinson R.22 than Heath Robinson. Or were Shorts taking the Mickey as usual?

I think it was pitched at something later, such as AH.246, AH.247 or AH.248.

It was the heaviest aircraft in the world when it flew.

There was a differences.

My point is they didn't need to build a special X-plane to figure out how to do it.  They just said, "we need this" and did it.

mentions of Short PD.66, PD.67 & PD.68 helicopter proposals ? latter two in conjunction with Hiller ?
