Would it be possible for you to colourise my icons? If so, a wintry one would be lovely.

Coitanly. I shall add it to my list of things to do.

What is that thing? Who designed it?

That thing was a british proposal as part of the design process which led to the Chieftain tank we all know and love.

It was known as PROJECT PRODIGAL.

PRODIGAL 3 was for an air portable vehicle with a range of 500 miles (800km) crew of 1 or 2, weapons being fed by autoloader; armed with a 160mm Low pressure gun firing a 60 lb HESH round at 600 m/sec. Liquid propellant was a possibility, as was a recoil-less mount.

Unfortunately, the book doesn't show any pictures of it.

The one with the two guns is the final specification for FV 4401:

Cost must be 1/4th that of Conqueror
Rolls Royce Series B Engine
2 x 120mm Recoilless Rifles based on the current infantry weapon (BAT)

Each gun was to be fed by rotary magazines, each containing seven rounds.

A Coaxial MG was to be fitted, along with a spotting rifle for rangefinding.

The Weapons could elevate +10 deg, and depress -7 degrees, same as Conqueror.

Apparently three prototypes of some sort were made; under the name "Contentious", and at least one is at the tank museum in Bovington.
