Transistor radio, 1958

Anyone who has used an old tube-type radio will remember the wait after the on button was actuated. It took a minute or so for the sound to start as the vacuum tubes warmed up and started functioning. Not so with the transistor radio, instant on! These new battery operated radios were also portable so your music could accompany you on picnics, to the beach etc. Really a great technological leap. 

This unit also advertises that it can act as a tuner for your home stereo, not sure how that might work in the days before Bluetooth or USB cables.

Whipple File factory

  Ballardvale, located north of Boston Mass. was a mill town, known for cotton and woolen mills. Another operation was the Machine Shop, established in 1847 by John Marland. Here machines of various types were made, including steam engines. In 1860 this mill was sold to the Whipple File Manufacturing Company. By 1866 Whipple File had a capital of $1 million, a building site of 4 acres, and employed 600. By 1869 it failed, apparently due to mismanagement. Has anyone ever seen a file with the Whipple name on it?

Long distance Naval flight

 In 1925 the US Navy, wanting to show they were up with aviation times, attempted a non-stop California- Hawaii flight with two PN-9 flying boats. These were an American development of the British Felixstowe F-5. Two aircraft were used, one was forced to land on the water only 300 miles after takeoff. It was rescued and towed back to San Francisco. The second plane flew 1841 miles before it ran out of fuel and was also forced to ditch in the sea. The crew jury-rigged sails from wing fabric and sailed another 450 miles in 10 days before being rescued off the coast of the island of Kauai. Hard to believe that was 99 years ago.

 The plane was later used in another long distance flight over the Caribbean where it was forced to ditch once again. This time it was sunk as a navigation hazard.

Bikes in the 'hood, CBX

Nice to see a CBX being used, they're still an impressive piece of machinery. Note the ventilated discs! This is the 1982 touring version.

The Denbigh Drilling Machine

Here's a big beautiful drill on display at the Brooklands Museum. The Denbigh Engineering Co was located in the industrial area between Birmingham and Wolverhampton, where they manufactured heavy machine tools mostly for industry. Not sure when the company started in business, but according to lathes.co.uk, they lasted till about 1970. Wouldn't that machine look great sitting in the corner of anyone's shop?

1927 Triumph tank construction

This is the tank from a 1927 works Triumph showing an interesting treatment of the edges of the various sheet metal parts of the tank, The scalloped edges make for a stronger solder joint (in the days before welding processes). Seen at the Sammy Miller Museum.
