Think they're Copplestone 'Savages' sculpts mainly from his Future Wars range for Grenadier (now carried by EM4), apart from the guy in the topper, who's from his own Future Wars range ('Wasteland Desperadoes' pack).
Pretty much as Captain Blood said. From left to right they are:
Old Grenadier/Copplestone savage (EM4 code: 0031):
http://www.em4miniatures.com/acatalog/SAVAGES.htmlConverted his SMG to a hand-flamer using a 1/35 panzerfaust
GW Necromunda miniature:
Removed some obvious icons. Added a double tank for the flamer from the spares box, Modified the gun to a heavy flamer with a (thick solder) fuel-pipe and Tau(?) igniter
Copplestone Castings (FW47): Wasteland Desperadoes:
http://www.copplestonecastings.co.uk/images/fw47col.jpgUnmodified miniature.
Old Grenadier/Copplestone savage (EM4 code: 0030):
Removed the sashimono, cut down the shotgun & converted it to a crossbow. Added greenstuff harness straps and mohican.
Old Grenadier/Copplestone savage (EM4 code: 0025):
Removed the knife from his left hand and replaced it with a spare (Foundry gladiator?) shield
I can post some photos of the unpainted conversions after the round is over
I see more evildoers queuing up to kill poor old Mad Max in your 'Tanker Chse' game
I've wanted to do a wider range of post-apoc games for ages. I did the conversions at least 2 years ago but they have sat on the shelf ever since. The LPL means I finally splashed some paint on them.
