Sadly, it seems whenever a collector of maritime uniform insignia comes across a Federal-style shield with three white stars, automatically the assumption is the insignia comes from the United States Shiping Board (
These cap badges are the official insignia of the National Organization of Masters, Mates, and Pilots (NOMMP). This group was (and still is) a bargaining unit for Deck Officers aboard United States-flag vessels.
The assumption is quite easy to make since NOMMP’s cap badge looks very similar to the insignia worn by USSB employees. However, some also forget that USSB was abolished by Executive Order 6166 of 10 June 1933, and all its functions, including those with respect to United States Shipping Board Merchant Fleet Corporation, was transferred to United States Shipping Board Bureau, Department of Commerce, effective 2 March 1934 (at this point USSB no longer issued independent annual reports); USSB separation of employees was deferred until 30 September 1933 by Executive Order 6245 of 9 August 1933. The Bureau’s functions were assumed by the United States Maritime Commission (USMC) on 26 October 1936, pursuant to Act of 29 June 1936 (49 Stat. 1985). A chart detailing the Emergency Fleet Corporation’s lines (which USSB managed) from 1919 through the dissolution of federally-managed lines in 1940 (as under USMC); the chart is here.
Although not stated in the description, the design elements are fairly straightforward. The wreath is the same as used on the
S. Appel & Company on 14-18 Fulton St. in New York was the official distributor and manufacturer of the insignia. They provided both embroidered, and stamped-metal and enamel versions of the same.
The raison d’être for the creation of distinctive insignia is due to the fact that during the mid-1940s, NOMMP wished to distinguish itself from the newly-minted and not-always unionized mariners in the United States Merchant fleet. Since shipboard uniforms were not codified by law, NOMMP tinkered with the dress of the day. Unlike the confusing array of regulations for United States Maritime Service (USMS) officers with appointed rank based upon ship tonnage, NOMMP used lace stripes to designate position aboard a vessel. Buttons were adorned with plain anchors – which in practice was not the between war anchor button – rather the anchor and two stars design used at the time by the United States Merchant Marine Academy Cadet Corps.

Sometimes NOMMP members made do with cap badges they had on hand and painted them.
