The supply wagon is a Lledo milk-float with an added tissue paper canvas cover. The driver is from a pack of figures I got from the bring and buy at an old SOTCW event many years ago. I think they might be Crimean War era British.
The gun is a French 75mm Mle1897 by Raventhorpe. Up to now it's been serving I'm my 1940 French army but I have some unbuilt pneumatic-tyres 75s so the French will get those instead. Again, the unidentified gunner figures. They were painted in the same colour as the infantry (khaki with a sepia wash) but with chocolate brown busbies with cobalt blue bags.
