In March 1973 Almark added some lead World War 2 figures designed by Charles Stadden to their two existing sets of plastic British Infantry and British Infantry weapons.
These are very elegant figures which were sold shrink wrapped onto display cards.
An original advert from Almark's Modelworld magazine from May 1973 is shown, together with pictures of some actual figures.
Information on the two plastic sets is available on Plastic Soldier Review:
