Hinton Hunt issued a series of plates drawn by Gerry Embleton, together with painting instructions. I am not sure whether these were aimed more at their 54mm figure customers than their 20mm ones. Whatever the case, they were attractive and useful painting aids. Thanks to John and to Richard I have had access to a nearly complete set, and have posted them below, as part of my drive to preserve some of the Hinton Hunt ephemera.
The original description and lists of Prints Militaire from the big Hinton Hunt catalogue are reproduced below.
