A couple of recent conversions...
The elderly gentleman on the left started off as a GZG civilan/colonist, the one on the right is a GZG armed civilian/colonist with a ZG gasmask conversion head.
I decided that the population of my colony are in need of a patriarch of some sort. I started with a GZG colonist, added a beard sculpted from epoxy plumber's putty and a walking stick from a guitar string.
I also wanted to use some more of the GZG conversion heads which I've had for a while. A couple of my armed colonists have lost their heads and received replacements. The middle figure's head was carefully sliced off (may re-use it elsewhere), the figure on the right had his head removed with a pair of cutters as it was too difficult to do with a knife. Both had holes drilled with a pin-vice, and the heads (with about 4mm of stalk still attached) araldited into place.
The elderly gent out for a stroll with a fellow colonist - possibly a son judging by the familial resemblance!
Before & after - an armed colonist and his rather sinister gas mask wearing friend.
