I found something on YouTube today and am passing it along.Someone has loaded some actual training films on the Daimler Armoured Car ( 2 pounder gun),and these are very well done.The first is "Daimler Armoured Car external details", then there is "Daimler Armoured Car interior details" (

There is also something done on the Humber armoured car as well.
