It was originally named the MMJ 5.7mm [1] by its designer and is also known in the U.S. as the 5.7mm Johnson, the Johnson MMJ 5.7mm Spitfire, and the .22 Johnson, (or 5.7×33mm internationally).

1927 Johnson Seahorse outboard motor at the Tellus Science Museum. The original company that made Johnson inboard motors and outboard motors was the Johnson Brothers Motor Company of Terre Haute, Indiana, United States. They started building inboard 2-cycle marine engines in 1903 in a barn behind the house, along with matching boats.
The piezo measuring device (transducer) is positioned at a distance of 25 millimetres (0.98 in) from the breech face when the length of the cartridge case permits that, including limits. When the length of the cartridge case is too short, pressure measurement will take place at a chambering specific defined shorter distance from the breech face ...

In the early 1980s, High Standard Firearms had been dealing with financial problems and had to cease derringer production in 1984. Benjamin Johnson Technologies scaled up the design, into a .38 Special pocket gun known as the DA38 Derringer. In 1990, the design went to the American Derringer Company. [2] [3]
The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun. However, except for the barrel length and the use of semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft.
As more classes were founded, Johnson moved on to B's, C's, D's, and E's. Johnson was commissioned to build the 16 ft X-Boat for youth in the 1930s. Johnson designed the J-Scow in the mid-1950s which was converted to the MC. [clarification needed] Through the years, the boat builder built Optis and 420s. In 1994, the builder brought out the ...
