Original Wwii Army

There is always a small flat unpainted area on nearly every piece of German artillery near the breach, that is where this would be placed and clamped down. This would allow you to calibrate the mounting of the sight block. It is in decent condition except for the bubble level, which is smashed.

See photos for size and condition. I know there should be a simpler way of doing this, but I haven't figured it out, so this is my best option at the moment.
