A full service instrument shop specializing in sales and service of marine compasses. Suppliers of genuine replacement parts for Danforth, Aquameter, Ritchie, Kelvin White, Dirigo and Star compasses
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.
To determine which size Constellation you have, measure the diameter of the clear dome.
