I have just placed a suggestion in the Eureka Miniatures site's 100 club (
http://www.eurekamin.com.au)
I would like some 28mm figures in mountain climbing gear from 1900-1945. Woollen clothes, big goggles, hemp rope, huge ice axes and so on. You don't actually need them in the cat of climbing but they would be sculpted as if on ledges, base camps and summits. Maybe old large format cameras and so on. They can do double duty as Polar explorers.
And let's face it, you need a thumping great climbing axe when a yeti appears in front of you.
Please show an interest in this small project as I have not seen anything much in this line other than a few unsatisfying Polar sets.
