Judging by their very limited use in teeth arm units by the time of the NW Europe Campaign, the majority must have sat in depots and it seems amazing they were still making them by 1945, long after Humber LRC production had been stopped.
If the British Government had done the sensible thing like the Americans and instructed manufacturers to make other companies products, the only wheeled armoured in service would have been Daimler Armoured Cars and Scout Cars. By the end of the war most of the Recce Corps Units had been re-equiped with Daimlers, but there were never enough to go round.
