Rare EAGLE LEVEL CO. 6″ Brass Adjustable Sighting Level

Patented Oct. 21, 1890 by Charles G. Smith of Washington, DC. This is only the second example I’ve seen. Both vials are full and working and are original. Lines are marked on the plaster under the vials – this was sometimes done before lines were added to vials themselves. All parts are present and original. No cracks or damage to the lenses or mirror. Everything works as it should. A rare and really cool little level. Definitely has that gizmo factor!
