If you want some perfect Necromunda Orlock female models, check out "Female Miner Gang with Mixed weapons" from shapeways (
http://www.shapeways.com/product/92UL6P8XM/female-miner-gang-with-mixed-weapons) modelled by notnorm.
They have perfect scale (bulky heroic 28mm identical to
GW) and comes with mostly relevant weaponry. I made two conversions, adding a boltgun and a autopistol. These models are fragile to convert and shatters easily so it's safer to use dremel than knife.
Unfortunately northorn has a very limited selection of models for sale. Seems like there used to be more but they may have been removed. Anyone know what happened? Or if there will be more models? There are also some Delaque female models for sale, but not much else.
