Whilst looking for some images of Hinchliffe Models' chariot pieces to solve another puzzle, I came across a February 1975 advertisement on the wonderful old catalogue resource Mirosoft... I've used it many times before and, indeed, foresee using it a lot in the future... Anyway, searching through a Hinchliffe Models' ads PDF I finally found a title for SF15 which has, so far, been an unknown... most listings jumping from SF14 to SF16... we finally have SF15 Martian Dog. So, a partly solved puzzle now needing a picture of a Peter Gilder sculpted Calot.
More on the full range here;
SF1 Red Martian officer
SF2 Red Martian trooper, radium rifle
SF3 Red Martian trooper, long and short sword
SF4 Red Martian Female, radium pistol
SF5 Black Martian trooper, radium rifle
SF6 White Martian, sword, attacking
SF7 White Martian, sword, defending
SF8 Green Martian, swords
SF9 Green Martian, sword and axe
SF10 Hero, possibly John Carter himself!
SF11 Red Martian Princess
SF12 Giant Martian Ape
SF14 Martian Lion
SF15 Martian Dog
SF16 Red Martian trooper, mounted on Thoat.
SF17 Green Martian mounted on Thoat
Lots of info on John Carter ranges below (although it does need an update);
Any thoughts please leave a comment or give me a shout on firstname.lastname@example.org
