For those of you who have access to the IRRS photos on Flickr there is a great picture of 18828 a CIE H van one of the 18762-18861 batch built 1958 , 18828 was one of 15 fitted with vacuum brakes 1961/62 and pressed steel ends and sliding doors , a forerunner of the 1964 introduced Palvans 26000 but the dimenions are more similar to the standard H van , the 18762 series were painted green with flying snail black ends for their use on passanger trains , eventually they would be painted standard grey.
