I am going to get the print and see what the Census Number is!! I could just doi with that photo at the moment. I think, from the front rad design it might just be one of the two Guy Quad Ant prototypes from late 1937, although only trialled in 1938. Looking at the caption I think that is what it is...either the diesel-engined or petrol-engined one, the former had four-wheel steering. H 385731 & 385732 supplied under V.3168. Can anyone suggest if this one has a winch or not please?
I have just checked the IWM site

..if you type in 'KID' and nothing else in the 'PHOTOGRAPH NUMBER' space on the page and then select at the drop-down box 500 images to be viewed, yyou get say 285 images. However type in 'KIDBROOKE' in the 'SUBJECT' box and then select 500 images, you get many more! !
A better suggestion is typing in 'MINISTRY OF SUPPLY' in the 'SUBJECT' box, as it reveals all the Kidbrooke photos, as well as a few gems such as Carriers.
To explain, Kidbrooke was the Ministry of Supply offices at the station of the same name failry near Woolwich in South-east London. The vehicles were tested there and photographed sometimes on a village green a few miles away..you get to recognise the same location
