I decided to go with a standard black scheme for this piece. The main chassis is black with a Boltgun metal chipping at the extents (my Boltgun metal is still a runny paint which can not be said for the other 4 Leadbelchers I have had since the new range! Sorry just had to get that out), this was done with a sponge and tweezers.
The main tracks were done with Boltgun metal washed with Leadbelcher and drybrushed with Ironbreaker. I will be adding some more grime and dirt later I reckon.
The brass work was done with dark golds and various brass or bronzes, washed and layered / chipped up.
