Anyone in the United States who has owned a gasoline powered lawn mower has had it most likely powered by a Briggs & Stratton engine.  In 1953 the company introduced light-weight aluminum engines that were found on many mowers of the era.  The first gasoline powered mowers I used for mowing lawns were Briggs & Stratton.  To me, Briggs & Stratton was synonymous with lawn mower engines.  I did not realize there were other manufacturers of the same type engines.  For the early mowers, the pull rope was separate from the engine.  To start it, the rope had to be manually wrapped around the engine pulley.

With this sort of background, I expected to find examples of small gasoline engines used for various applications.  The one that is most prevalent in restored military equipment are Briggs & Stratton generators to power multiple gun mounts.


This is a Briggs & Stratton gasoline powered generator for an M45 Quad Mount anti-aircraft gun.  Author's photo.


Briggs & Stratton won the Army-Navy "E" Award in August 1942.

This M16 half-track was on display at the 2021 Findlay, OH Military Show.  This particular M16, named "The African Queen" by the owner, has been on display at the National Museum of the United States Air Force since December 2020.  For the Findlay Military Show, the owner temporarily removed it from the museum for it to be part of the Findlay event.  This allowed me to obtain photos of the gun mount and Briggs & Stratton engine not afforded me at the National Museum of the USAF.  Author's photo.

I was allowed to climb up into the rear of the vehicle that allowed a photo of the top of the engine.  Author's photo.

The data plate for the Briggs & Stratton engine on "The African Queen" shows that it is serial number 15519.  Author's photo.


There was a second M16 at the 2021 Findlay Military Show.  Author's photo. 


The M45 Quad Mount on this M16 is operational and has a battery installed which used the Briggs & Stratton engine and generator charged.  The battery then operates the traversing and elevation system on the gun mount.  Author's photo.


The pull rope can is stowed just at the bottom and rear of the engine.  There is no data plate on this unit.  Author's photo.


This Multiple Caliber .50 Machine Gun Mount M45 is mounted on a small trailer and was used for fixed anti-aircraft gun positions.  The small wheels on the trailer hindered the movement of the unit.  The Briggs & Stratton engine can be seen mounted in the rear of the gun mount.


The M17 trailer was another method of transporting the M45 during World War Two.  With the larger tires, it had good mobility.  The Briggs & Stratton engine is visible to the rear of the gun mount.  Author's photo.


While small motor generator units like the P-1 series used on M45 Quad Gun Mounts were adapted from Briggs & Stratton's pre-war commercial product line, the manufacture of General Electric aircraft magnetos were not.  This R-2800-59 built by Pratt & Whitney has two GE magnetos on it that were manufactured under license by Briggs & Stratton.  This engine and magnetos are on display at the Evansville Wartime Museum in Evansville, IN.  The P-47 in the background was one of 6,225 that was built during World War Two just a mile to the south of its current location.  Author's photo.


The GE-designed magnetos are called turtleback magnetos due their distinctive shape.  Author's photo.

This is the General Electric magneto on the right side of the engine.  Author's photo.


I was completely surprised to find that a company that is most well-known for its lawnmower engines had built aircraft magnetos to help win World War Two.  In 1947 General Electric published a book that told of its efforts in assisting the war effort.  The book, entitled "Men and Volts at War" is very comprehensive on all of the products that GE built during World War Two.  However, there is no mention of aircraft magnetos either being designed or manufactured by the company.  Obviously, GE designed aircraft magnetos because the data plates on the magnetos note they are of General Electric design.  Apparently, with all of the other products it needed to produce for the war effort, it did not have the manufacturing capacity to build the magnetos, and the work was given to Briggs & Stratton.  With no evidence that GE built any magnetos, this implies that Briggs & Stratton built all of them. 

On this particular magneto, the serial number and other information is not legible.  Author's photo. 


The left hand magneto is serial number 132724.  Both magnetos are Type s18LG-P1.  Author's photo. 


This is a cross sectional view of a GE aircraft magneto.

Every engine had two magnetos implying that Briggs & Stratton built 67,236 magnetos for OEM engines plus spares and spare parts.


This Ford-built R-2800 is on display at the Yankee Air Museum.  The R-2800-7x is either an R-2800-71, 75, or 79 engine, as it is not possible to identify the last digit on the data plate. It is one of these three types as it has the GE magnetos on it.  Author's photo.

This Chevrolet-built Pratt and Whitney R-2800 engine is on display at the National Museum of WWII Aviation in Colorado Springs, CO.  It is equipped with Briggs & Stratton magnetos.  Author's photo.


The engine is part of a larger display showing how the Republic P-47 super turbocharger system worked. Author's photo. 


This P-47N is located at the Peterson Air and Space Museum at Peterson AFB in Colorado Springs, CO.  It has a Chevrolet Tonawanda, NY-built R-2800-73 engine in it.  Author's photo.


The left Briggs & Stratton-built magneto is visible at the top of the engine.  Author's photo.


This P-47D Razorback is on display at the National Museum of the United States Air Force.  It has either a Pratt & Whitney or Ford-built R-2800-59 engine installed in it.  Most likely it is a Ford-built R-2800-59, as there were 20 times more of them built than the Pratt & Whitney version.  Author's photo.


The distinctive turtle back magnetos built by Briggs & Stratton are visible at the top of the engine.  Author's photo.


This P-61B is undergoing restoration at the Mid-Atlantic Air Museum in Reading, PA.  Author's photo.


The R-2800-65 with the P-61 was built by either Nash-Kelvinator or Pratt & Whitney.  In either case, the engine has Briggs & Stratton-built magnetos on it.  Author's photo.


This P-61C is on display at the National Museum of the United States Air Force.  The P-61C featured the higher performance R-2800-73 that Chevrolet was assigned to build and equipped with Briggs & Stratton-built GE magnetos.  Author's photo.


Ford built 6,617 R-2800-79 engines with the Briggs & Stratton-built GE magnetos for the A-26B.  Author's photo.


The Curtiss C-46 Commando was the largest twin engine transport used by the US in World War Two.   8,042 R-2800-75 engines with Briggs & Stratton-built GE-designed magnetos were built by the Ford Motor Company for the C-46.  Author's Photo.
