On the subject of Dinky Toy copies here are a couple more by Kemlow. They were mainly known for their range of railway accessories, but did make a small range of military toys.
The Bedford truck (or 3-ton Army Wagon) is a good copy of the Dinky toy but does not have a spare wheel under the tray. The ammunition limber is completely different from the Dinky model but the 25pdr gun is reasonably similar.
The Armoured Car is also a good copy of the Dinky toy but has no base.
