Khurasan Miniatures have posted photos and background for their upcoming 15mm Los Viejos miniatures.
From their website:
The Molch Vornid War brought many mercenaries and guns for hire to the Molch sector to earn a living or get their kicks on the field of battle. Of all those, the most famous shots to participate were, of course, Los Viejos.
Hailing from Texmex 3, Los Viejos moved their herds of Landgrubs across the deserts, and while on the trail spent much of their free time target-shooting with their Foal Peacebreaker pistols, which fires a cartridged plasma round without any recoil. So accurate are they with these powerful long ranged pistols, even when firing from the hip, it is said by some that they have never have missed anything they shot at. Whilst the accuracy of this statement has been questioned, the accuracy of Los Viejos has not, and all sentients live in fear of a duel with these small but formidable creatures.
