Miniskirt, a Honda 90 and the Monkees, there's the sixties right there.
We used to make things in this country #374 DMP Minibikes
Lots of manufacturers were getting involved in the motorized leisure market in the late sixties and early seventies. Delhi Metal Products produced a line of minibikes, this Rupp clone Trail-Champ has full suspension and the inclined Tecumseh motor with torque converter.
Delhi Metal Products was a supplier of fans for furnaces and air handling systems, also antennas and other metal products. The company was bought by a US company General Instrument in 1973 for the antenna business. I suspect that was the end of the minibike production.

Scott Trivan
In 1929 Scott motorcycles was working on an air cooled single cylinder 298cc engine to expand into the lightweight market. That motor was not a success but plans were already in the works to use that engine in a three wheel delivery van. A few prototypes were made and a company- S. A. V. Light cars was set up to market it but soon disappeared.

Traveler
Here's a minor little sharpening stone, sent to me a reader in New Jersey (thanks, Jay!). He said he had found this promotional item from a company in Brampton, Ontario (near Toronto) at a sale in New Jersey. It would be fun to learn how it actually ended about 540 miles away from home.
We moved to a 10 digit phone number format in about 2001 so it must be at least 25 years old. The company seems to be still in business today.

GSXR-1100 auction find
Hard to believe this thing is 40 years old, knocked us all for a loop when it was released. Missing some fairing pieces, but surprisingly complete otherwise.

Cleveland Discol gasoline
Tetraethyl lead was introduced into gasoline as an antiknock additive in the 1920s, it made possible high compression engines, greatly improving efficiency and power.
Discol gasoline was introduced in 1932 by the Cleveland Petroleum Company, using ethanol as the anti-knock additive. "Discol" was a contraction of the Distillers Company which produced the alcohol. Who knew that the additive would replace leaded gasoline 60 odd years later.

Nicholson wrench
Little implement wrenches like this show up all the time at antique stores, generally part of the tool kit supplied with agricultural equipment, in this case one of products that W. N. Nicholson and Sons of Newark-on-Trent, Nottinghamshire exported to Canada.
The company was formed in 1825, as a malleable iron and steel foundry and according to Grace's Guides, they were still in business to at least 1960. Over the years they manufactured agricultural machinery and food mills of various kinds, also boilers, steam engines and stationary gas engines.

Frazer & Jones
I thought this was just another wrench from a long-gone 19th century agricultural equipment manufacturer, it's good to see that Frazer & Nash is still around casting iron in Syracuse, New York.
From their site, the company was established in 1845 as Frazer & Benedict, became the Frazer & Jones Company in 1882 and was acquired by the current parent company, The Eastern Company in 1945. Their business is medium to high volume castings less than 25 lb. No hulls for Sherman tanks or steam locomotive tender frames
I expect this wrench probably dates to their early days.
Hoffar homebuilt sea plane
In 1917 Vancouver boatbuilders James and Henry Hoffar built this seaplane. Not too many details but it apparently flew successfully but was later destroyed when it hit a log in the water.
From this experience, the boatbuilders acquired a contract to build a 2 seat flying boat to be used as a fire patrol craft. It also was successful on a few test flights, but suffered engine failure as it flew over the city. It crashed into the roof of a house and was destroyed.
In 1929, Boeing acquired the Hoffar-Beeching yard and used it to build their seaplanes.

I was recently catching up on the Pennsylvania Railroad T1 Trust steam engine reconstruction and noted that they are constructing the main frame as weldments instead of the original castings. I guess that makes sense, casting huge pieces of steel isn't as common as it used to be, the required strength of the frame can be determined by using FEA, the casting can be redesigned as a weldment. Pieces are laser cut and then welded together, no issues, it's a tried and true technology. But I remember reading about large (huge) castings being made more than a hundred years ago, whole 50 or 60 foot long steam locomotive or tender frames being cast in one piece, armour plate tank hulls cast in one piece... Those guys were massively skilled.

The Blitzen' Benz
Fitted with a 21,504 cc four cylinder engine producing 200 hp at 1500 rpm, this car achieved a speed of 127 mph at Brooklands in 1909, piloted by Hector Hémery. A year later Barney Oldfield went even faster- 131.7 mph on the beach at Daytona.
