I found a very nice cast iron 24inch bubble inclinometer at a yard
sale. I don't have the unit in front of me and can't remember the
manufacturer but I remember that its patent date was around 1892-1896.
The center is a rotating brass insert with the graduations in degrees
are around this brass insert. The glass bubble is empty and I assume
its cracked somewhere. All the original japanning is intact, light
surface rust and appears to have been well taken care off.

I'd like to have this item repaired and re certified if possible,
anyone know where I might get this restored?
