David Fletcher comments:

HHX760...was a prototype armoured command vehicle on a CS11/30 chassis which served as the ‘Experimental Armoured Office’ in Headquarters 1st Tank Brigade for the 1938 season. It was a one-off rival to a hideous looking Leyland design on the SKG1 chassis. Rather than adopt the type the War Office had 15 from the CS9 order altered to a similar shape but naturally a good deal more cramped.

So, MUCH rarer than Quaggas!
