The Scots Greys
were active in North Africa. "April V" and "Allysloper"
were two of their Grants, along with "Aigreadsios II"
(Airgeadsios mispelt, incomplete marking). All were named after
famous race horses of that time period (thanks to Ken Jones for
his splendid research effort!)
The remaining
options are Aussie's 2/9th Regiment Grant, an M3A2 chassis with
interesting Australian army camouflage, 1st AD (UK) Grant with the
famous blue-squared "8" (complete with WDN), and 3rd CLY's
uniquely-marked pair of Grants ("Defiance III" and "Stowford").
Ken Jones aptly called "Defiance III" a "moving billboard"
as it was painted with sorts of markings on its front fenders.
