Marmon Herrington Armoured Car MkIV

[Ferret1]

Looking for information and photographs of MkIV armoured cars in service - I am currently restoring one in the UK and am desperate to find out more information. This seems to be one of those vehicles that every one knows about but there seems to be very few pictures - the standard one which is in most books.....

if anyone can help I would be most grateful
