Indeed, the 12-inch Oregon gun Ericsson had built in England,
and which also constituted the U.S.S. Princetons armament
(along with the infamous Peacemaker of Captain Robert F. Stocktons build) was
worked by an equally-revolutionary iron carriage of his own design.
and yes its too tall and its sides are too thick, but I got my gearing in
there and the siding disconnecting crank shaft. I tried to use the 2817 part but
I need 1.5 stud spacing to mesh the 8 and 16 teeth gears. I looked at 24 tooth
gear but that would make the gun carriage even taller!
I would be glad to see a better way to mount my new guns!
