Until I read this ad, I didn't know what BTH stood for. In the context of this 1949 ad, BTH competed against Lucas to sell devices to deliver a reliable spark to a motorcycle engine.

I originally thought it was a 911 having had some terrible things done to it, but I understand it's a Opel GT on top of a Lincoln chassis. The ad was in a 1979 magazine, too early for Photoshop. Liberace bought one apparently.
Many years ago, I happened upon this special at Daytona, yes that's a Harley Davidson XR motor crammed into a 1986 aluminum GSXR chassis. I waited around for the owner and tried to take better pictures from different angles... but in the end this image is all I have.
This big cast iron machine, found at an Ontario antique store, was designed and made by the Beno Gundlach company of Belleville, Ill. From info online it seems to be either an asbestos shingle or floor tile cutter. The cast-in handle hole would indicate its portability, but at 3 feet long and probably 70-lbs that might be subjective.
Company history here.
In the 1930s, speed record setting was all the rage, various British drivers held the world speed records since the twenties. In 1935, Malcolm Campbell had with his series of Bluebird cars, achieved 301 mph at Bonneville, John Cobb and George Eyston took turns moving that record to 350 mph by 1938.
Against that backdrop, Hitler had decided a German car with a German driver should hold the land speed record and he picked Auto Union race driver Hans Stuck to do the honours. Stuck then contracted Ferdinand Porsche to design and build a suitable car. In March 1937, the car shown here was presented. Designated the T80, it was originally to be powered by a Daimler Benz 34 liter V12 airplane engine giving 2200 horsepower, but with the speed records being raised at Bonneville, that engine was replaced by one of 44.5 liters, also mounted in the inverted orientation.
In the meantime Hitler had decided the record should be set on German soil, and in 1939 a nine mile section of the autobahn was prepared and it was decided that a record setting run would be made in the summer of 1940. However, all the plans came to nothing when Hitler sent troops into Poland in September of 1939. The T80 never ran at all.
Looking at the car, the driver was to sit in a narrow cockpit right in front of the engine. The 27 foot long car was fitted with 2 drive axles for traction, horizontal winglets provided downforce and the bodywork covering the rear wheels blended into tailfins for directional stability. And all that power and weight running on wire-spoked wheels!
There were a number of manufacturers who made 3 into 1 pipes for the two stroke triples back in the day. Though they were styled to look like an expansion chamber, it's doubtful they were at all effective or efficient with all the confused soundwaves bouncing around inside them. I expect the same would be true for this setup, though considering the 180° power pulses, only one exhaust port would be open at a time... hmmm. Now where is Gordon Jennings' Two stroke Tuners handbook?

The Convair XP5Y-1 was part of a new generation of US Navy flying boats, the program was intended to utilise the technology of laminar flow wings and the new turboprop technology then being developed. The airplane, powered by 4 Allison XT40 turboprops driving 15 foot contra rotating props, first flew in spring of 1950.
Originally intended to be a patrol aircraft, the Navy soon changed its mind and asked for a redesign as a cargo and passenger version. Convair experimented with a landing craft version, and an inflight refueling tanker version was also tried but the era of the military flying boat had passed.
In all, 11 aircraft were built, but the continuing unreliability of the Allison XT40 engines caused a number of crashes and was the cause of the program being cancelled in 1958. The planes were all scrapped.
U.S. President Dwight D. Eisenhower in a 1914 Rauch and Lang Electric during the 1952 campaign The car was owned by his mother-in-law, Mrs. Elivera Dowd.
Rauch and Lang electrics were capable of 16-20 mph and 50-100 miles on a charge. The price point was about 4 times higher than a Model T. Referring to the previous post, these cars were not fitted with Edison's nickel iron batteries, though apparently Thomas Edison did own a R and L electric car at some point.
