Circle cutter bit

 A fine accessory for your brace and bit. Put it in the chuck, make the necessary adjustments and scratch your circle.

Know your motorcycle forks

This image comes from one of Floyd Clymers books, so I expect they're all American makes, I cannot find what M.M. or R.S. stand for. Any ideas?  There was an Italian manufacturer MM between 1924 to 1957 but too late for this. More girder forks here.

Barcalo Buffalo Nail puller prybar

This carpenters nail puller seems like an unusual tool for the Barcalo operation who made mostly wrenches and tools for mechanics. Too bad this one is quite corroded, but it looks like a good solid pry bar. We covered Barcalo in this 2016 post.
 

Isotta Fraschini

The Isotta Fraschini pushrod inline eight cylinder engine was introduced immediately after WW1 in this Tipo 8 luxury car. The engine was enlarged and improved over the years and was still in use 20 years later.
 

O.I.T. wrench

 Here's another middling-quality wrench from an unknown Taiwanese toolmaker. Maybe someday people will collect these unloved imported tools and we'll find out more about the manufacturers.

Sandow engine

 Detroit Motor Car Supply Co. of Detroit built a line of Sandow-named engines from 1912 till 1920. 

More info on the Sandow engine here.

 

Brooklyn Navy Yard drydock

 Another very early photograph. Taken in 1846, this photograph shows the Brooklyn Navy Yard's first dry dock being constructed. It was completed in 1850 and has been in operation ever since. The image below is from a 2018 article in Curbed New York. 

Allen brand ratchet

In 1910 William G. Allen  patented a setscrew with an internal (socket) hex for tightening the screw, this became known as the Allen screw and the Allen Manufacturing company was set up in 1913 to produce the setscrews and accompanying hex keys.  Although Mr. Allen left the company shortly thereafter, the company prospered, branching out into regular wrenches and related tool sets. Somewhere along the way they became part of the Armstrong tool company which was swallowed up by Danaher in 1994. In 2012, Danaher sold their tool business and it became part of Apex Tool Group. 

This ratchet has the Danaher era logo so must have been made post 1995.

1934 Austin Seven

I didn't hear the story, but how can something like this have survived this many decades without disappearing or being fully restored? British Car Day 2024.

thanks, Bruce!

 

1912 Airshow, loop the loop!
