The model is Privateer Press' Dirty Meg mercenary solo. She's unconverted, so I can still use her as such.

The body is from a Privateer Press Khador Field Mechanik Officer, with the shoulder plates replaced with those of a Rhulic heavy Warjack. I bought a second Dirty Meg from which I carefully sawed her head and the big mechanical contraption she carries on her shoulder. The latter is mounted here, on her left shoulder:

She doesn't have a name at the moment, as I built her mainly for the fun of it, instead of for a clearly planned character I or someone will be playing. Hopefully, someday I'll get to find out who she is. ;-)
