Over on The Old Metal Detector I have posted listings of the Minifigs 20mm (HO/OO) range, from this catalogue form around 1967. Interestingly it also contains early listings for S Range. so shows Miniature Figurines in its first major transition. I have shown the pages with S Range listings below. These listings contain wargame rules to buy, and recommends a number of information reference books, including Funcken (spelt interestingly) and the Kannik Blandford - more of this, perhaps, anon.
