Danforth, Kelvin White 8" Constellation Parts

Originally designed in 1947 by Wilfrid G. White of the Kelvin White Co., the Constellation series compasses were available in 5",6",7" and 8" sizes with the Kelvin-White name on them. The Kelvin-White company became the Wilfrid O. White and Sons Co. and the Constellations were made under that name until 1961 when Danforth bought the company and used the name Danforth-White on the compasses, finally dropping the White name in the late 1960's to become Danforth compasses. Danforth added a 4" constellation to the line. In the 1980's Rule industries bought Danforth and continued using the Danforth name. Rule added a 4-1/2" Constellation to the line. Contellations are still manufactured today.

To determine which size Constellation you have, measure the diameter of the clear dome. The 8" measures 8-3/8" in diameter. The 8" Constellation takes about 1.25 gallons of oil to fill it. Click on the schematic to enlarge the diagram.
