A few more details have been added to the overall structure. The breech block looks rough still but will be sanded smoother when I get to it.
A side view showing the additions of the elevation quadrant and the hand grip.
A closeup view of the elevation gear and the hand grip which was shaped from a piece of aluminium extrusion.
The inner view of the recoil guard, a bracket and tube have been glued in place on the left hand side of the actual mounting although they are not very evident.
