The Top figure is from the same Artizan pack as the BAR gunner. The other two are from North Star's SCW figure pack. The North Star figures are ok apart from the rifles which are a bit rubbish.
North Star's SCW figures. The rifle on the left has been changed.
The Artizan figure was easy, I just cut off the old rifle at the left hand and drilled down through the hand as far as I could. I then cut out the rest of the rifle from between the hands and drilled a little way in to the right hand.
With a TAG rifle.
I cut the left hand at the top to separate the fingers and make 1 thumb. The rifle had most of the butt cut off, just leaving a small peg. This peg was shaved down to fit in to the hole I'd drilled in to the right hand.
The fingers where opened out to fit the rifle. The rifle was glued in to place using the peg and on the left hand.
The North Star figure was even easier. The rifle and right hand had to be cut away, I then drilled up in to the arm and used a Musketeer rifle and hand from a Black and Tan figure to replace them.
