Progress has slowed somewhat on this, not a great time of year unfortunately, work gets very busy on the run up to Christmas.
Anyway, got the butt pack painted and finally got the right arm with the M79 mounted, just need to finish off the tiger pattern on the sleeve and I can start work on the trousers.
Tried a different approach on the metal parts of the M79, usually I use Gunze Sanygo Gunmetal which you can buff to a shine when dry. This time I just painted the metal parts with Vallejo Black Grey and used a make-up applicator to apply powdered graphite from a 4B pencil. Looks alright to me.
