5" Old Style Wilfrid O. White, Kelvin-White, Danforth Constellation Parts 1947-1980

The Constellation Series compass was originally designed in 1947 by the Kelvin White Company, which became known as the Wilfrid O. White Co..The early versions of this compass have a serial number stamped in the top bezel ring, the first two letters of this number on the 5" compasses began with the letters CB. Danforth bought the company in 1961 and continued manufacturing the compasses to this day. This diagram is of the earliest 5" Constellation which was manufactured in this style until the early 1980's when it was updated into what we call the New style 5" Constellation. The clear dome on the 5" Constellation measures 5-3/16" in diameter at the base. The 5" Constellation uses approximately 45 ounces of compass oil. Click on the diagram to enlarge the schematic. The key number in the diagram is the first number in the order number.
