Not the special in the video  but the same engine, a friend of mine had a brand new CB77 305 Honda Super Sport sometime around 1965, it made my bog standard 250 Dream look like it was standing still.
His Mum was widowed quite young as Stephen was only around 18 at the time, he was studying Languages at Uni. Not your standard French or Spanish but Arabic. I lost contact with him when his Mum moved back to the Isle of Man where he was born I think, the family name was Cooil that I believe is an old Manx name. The video of the engine triggered my memory.

He's quite knowledgeable about it and the design elements in relation to other bikes etc.

Slightly odd knowledge of welding though, as he notes it was brazed not welded (correctly it appears) but then notes "Bronze welding" as not used, which is brazing !

Wondered on initial closeup about that additional plate, the story of which came later ..... but oh dear, that welding is a bit of a shocker  :) dripping down the seam like candle wax  :) I'd take that off and at least get someone competent to properly braze a decent join down a replacement.

The frame is quite Tony Foale like in concept, also of "Bird cage" Maserati ilk too.

Nigel, there is a difference between brazing and bronze welding, although they are often referred to as being the same.
The main difference in the processes is the temperature.
Brazing is carried out at a lower temp and the brazing rod flows into the joint through capilliary action.
Bronze welding is done at a higher temp and melts the filler rod and parent metals together.

McCabe-Thiele (Ted):
The original Mini front wings were Brazed on at the factory IIRC.

If not then when mine were replaced the body shop said they had to be  brazed.
