|Clockwork Goblin Grizzly Walker (photo CGM)
A bit of Googling led me to Clockwork Goblin Miniatures 28mm World Without End miniatures line. I was aware that Clockwork Goblin produced alt-WW2 in 15mm, but not that they had a small 28mm range.
Aside from some nice German zombies, their range also includes British Automated Infantry, Soviet armoured infantry and this lovely looking US Grizzly walker.
Whilst Geheimkrieg is a little different from other alt-WW2 games in that it is a secret war that occurred in out historical timeline rather than an alternate history, I could not resist putting an order in for a Grizzly!
