  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. |
