Gilera at the top of their pre-war game. From 1935 till 1939 they produced this supercharged, liquid-cooled, DOHC transverse four cylinder race bike. Rider Dorini Serafini won the European Championship by winning the Ulster GP.

Sioux tools started as Albertson and Co in 1914, their first products being sparkplugs and piston rings, They soon invented and produced a lathe for turning valves, which started them in the tool market. This ad is from 1964 and they're still going strong today. Company history here.

Here's an interesting multi-use tool made by yet another long lost Canadian company, A&W in Guelph, Ontario. Update (see below)- Turns out it's actually A&V (for anvil and vise). The vise jaws are only about 2 1/2 inches wide so the whole tool is of hobby size though this thread suggests it dates to the mid 1800s. Wonder what the protrusions along the lower edge of the base are for?
Here's another combination vise anvil.
And an example of the American version is at https://www.garagejournal.com/
Comment here says: "Woodyatt and Guelph Malleable Iron were joined together into Taylor Forbes." https://www.flickr.com/photos/
I believe the following site is wrong based on the above: "Canadian manufacturers established at Guelph, Ontario in 1873. In 1890 they bought out A.R. Woodyatt." https://oldlawnmowerclub.co.
And a building that was home to both companies is still in use today: https://m.facebook.com/
More history on Guelph Malleable Iron Works, the other company folded into Taylor-Forbes!

Granville Bradshaw, who had many innovative engine-related designs in the first half of the last century, designed this oil cooled 500cc flat twin in the early 1920s. The cylinders were located inside the crankcase and were cooled by oil splash. The engine was derisively referred to as the "oil boiler" but it apparently worked well enough. He apparently believed the hotter an engine ran, the more efficient it was. Incidentally, this drawing is billed as the first fully sectioned motorcycle engine cutaway to appear in print, the artist's name is not noted and the signature is not clear enough to decipher.
Suzuki resurrected the oil cooled idea with its first generation GSXR SACS engines, where engine oil was circulated by a high volume pump and kept cooled by an oversized oil cooler (radiator). Increasing heat from higher output led them to adopt liquid cooling in the early nineties.

This largely unworn 6" Bessey vise was being thrown out at work. Take it away, they said. The screw assembly had broken so the jaws did not open. The swivel base would have needed to be removed to see what was required, I had no tools handy, it weighs 44 lbs, I don't need a vise project or even another vise. Sadly I left it there. Regrets.

This amusing ‘outfit’ was entered in a 1922 comic cycle parade at Coventry. Several of these old ‘penny farthing'” or ‘ordinary’ bicycles were entered, but the idea of attaching an Auto-wheel caused the "greatest amusement among the spectators.”

The tank and sidecovers were also used on the 650 Firebird, to my eye the styling worked better on this bike, the 250 Starfire. The low pipe model also looked nicer. The advertising company had to work pretty hard to sell these things when the competition was products like the Suzuki X-6 and the Honda CB72.
No matter how suggestive this ad is, animal skins were not used in the manufacture of flour sacks... though the actual material, cotton or paper, seems to depend on when this ad was written, the Lincoln paper mill was also the Lincoln cotton mill.

On March 28 1910, this unlikely craft, named the Hydravion , became the first aircraft to lift off and land on the water. Although others had experimented, Fabre was the first one to find the right combination of strength, lightness and the ability to break free of the water in the design of the floats. After 5 flights, he modified the craft to a rear rudder configuration and then crashed the it in a stall. Rebuilt, it was later wrecked in a gale. It now resides in the Musée de l'Air in Paris.
