Thanks. It was first suggested the anti-aircraft gun be pressed into the
anti-tank role during the defence of Dunkirk in 1940 so why it took so long
for the British to mount it in an AFV beats the hell out of me? Even when
they finally succeeded it was next to useless in having extremely restricted
traverse compared with the German 88 and Soviet 85mm tank conversions. Were
British engineers really that dumb they couldn't find a way of mounting a AA
gun in a fully traversing turret?

Even with the way it was done the thing was described as too heavy and
ungainly to be of much use and difficult to transport.
By the time they stuck a turret on it, you might be in E100/Maus territory.
That enclosed machine gun cupola atop it is interesting though; that
would later show up on U.S. tank designs.
The overall design though looks somewhat primitive, especially when
compared to something like a Jagdpanther.
Armor sloping is poor to nonexistent, and the whole thing looks way
heavier than it needs be.
It looks like it is to be used like a super assault gun, ala' the
SU-152, than as a tank destroyer.

If you really want to know, I suggest some light reading:
"Death By Design"
"The New Excalibur"
"Rude Mechanicals"
All of these books are authored by British authors, and all have
a pretty scathing assessment of the Tank Board, the group of officers
and gentlemen that were assigned the task of looking after tank
development for His Majesty.

I think you knew the answer to that when you posted this.
And, like most things, engineers have to design something to a
fairly specific set of requirements, and not "build us the best
tank that you can" type of requirements, either.
There was no requirement for the Tortoise to have a turret,
so none was designed. Same for the US T-28/95 GMC.

Check out two excellent books: The great tank scandal and Universal tank.
Both tell the story how the Brits "designed" their tanks.

H.G. Wells wanted in on the tank design process in WW I; if he'd had his
way, the tanks might have been a tad larger than they were:
