The" tank base" is from the Diamond tank transporter, here is another, with a intersting scene from the Korean war, a captured russian truck was used by the US forces as a railway car.
(This is true, I have an old picture of this)

Yes and no, the base is from Matchbox, the tank is Fujimi, sure, I's my model.
It is a T-34-85, the Matchbox model (now Revell) is a T-34-76, the turret is different.

You are right,
all Airfix railway range is now available from Dapol,
Airfix used 1:72 ( a little lie for the continent, there is 1:76 not popular .
In Japan, Fujimi had some military kits in 1:76, like this russian tank:

1:80, this scale do you have in Japan.
The reason is the other gauge from Japanese railkways (1067 mm), so they declare some kits in 1:80 (but is 1:76 in real.
As an example here is a model from Aoshima:
Mitsubishi Fuso Aero Star MP 37 is a heavy-duty single-decker bus produced by the Japanese manufacturer Mitsubishi Fuso since 2010.

When we have the Harvard, we need an Air Traffic Control truck, nobody made one.
So here comes the Airfix Matador with a new body, with some parts from matchbox and a checkerboard decal from Revell.
BTW, the Willys is the Matchbox kit.
