The figure – on the right in both images has been converted from the RSM French NCO on the left of both images.
Basically I’ve cut off the right hand, the left arm and the hat from the original figure. The right arm has been bent into a posture more suited to a walking or “advancing” pose, whilst the left arm has been bent a bit and glued on so that he might credibly be thought of as carrying his pole-arm. The amputated hat has gone onto the carefully sawn-off top of his head. I think this really changes the look of the figure, giving it a much more erect carriage than the original.
UPDATE: The figure also converts nicely to make a gunner hauling on a wheel, I've since found. I think I'll paint mine up as an infantryman pressed into serving a gun. I think the figure could also be capable of wielding a variety of artillery tools.
