Russell Hawkes 1919 planetarium has beautiful color and natural patina. If you rotate the sun mercury rotates around via the gear system. The rest of the unit has the gear mechanisms but seems stiff from years of non use. Piece comes with base that attaches via a nut to release the planetarium. The top case is not present but still an nice piece to secure the unit for transport. The brass sun has original patina and the base and numerals are clear—excellent wood color on the spindle. The most notable piece that has been worn is the globe. Most of the (around half) of the map has come off. I have shown both sides of the aluminum sphere—in my opinion I would leave it as is —adds more character to the piece. Measures 20” L and 12.5” H 9 (sun) without base.
