A post on Google+ caught my eye the other day with a picture of an old GW/Marauder/Citadel figure (here). These venerable old figs were for a predecessor to the necromunda rules. Crazy that back in the day GW would be making figures for a incomplete essentially unplayable system. I remember collecting White Dwarf magazines with fractions of these rules hoping to play, and even trying to make a gang (essentially unplayable due to the entirely random gear).
The figs themselves were quite characterful however, and numerous people picked them up, and eventually used them as human defence forces, or chaos cultists. I managed to get 3 of these guys in a trade, or cash purchase. I was playing necromunda (the spiritual successor to the confrontation rules) a lot at the time, and these guys fit well with my cawdor gang (masked religious nutters), the crimson zealots. The GW painted cawdor team was blue with a bit of red. I didn't want to copy exactly, but lacking a big sense of what colours might work well just inverted the scheme. I was happy enough with the results.
