Model Cannon. Last (?) Teardown.

Most parts are made. A few refinements and modifications still on the list. My sister in law is impressed, and took the first photo below.

About to commence the teardown, for final rivets and other fasteners, and some paint and lacquer. And the sights.
The undercarriage, slide and platforms and gear train, carriage with recoil cylinder, elevation gears, barrel, stops, handles.
