Update 2:
Being working on the rotation assembly the last couple days. I'm not sure if the original model was designed to actually be able to move, and its hard to tell from the pictures, so I've had to do some redesigns to get it to work. I'm planning on roughing up the metal and doing more minor tweaks to better match the rough details in the reference once the whole model is completed.
Going to be working on the barrel assembly and vertical rotation mechanism next.
