WW1 Era Crested Ware Red Cross Ambulance – Arms of Cambridge

A WW1 era crested ware Red Cross ambulance decorated with the arms of Cambridge Borough, unusually there is no makers mark to the base, it comes in good condition, there are two chips on the bottom of the wheels but these have been glazed which shows it was originally retailed like it and I think it had a radiator cap but this is missing, it measures 4 inches long.
