Boulton Pins and Buttons
Description: When I was a kid this was the first Air-fix model plane I made. First flown in 1939 this interesting fighter looks back to a time when gun turrets on small aircraft was the done thing. The changing nature of war unfortunately lead to a mauling at the hands of day fighters who learned the plane couldn't shoot forward. It ended up all in black and flying at night where it was an effective weapon against night bombing.
Description: Great for WWII airplane aircraft lovers, enthusiasts who love classic British aircraft, aviation model makers and buffs. Perfect for wwii era aviation aircraft memorabilia collectors showing a detailed blueprint line drawing diagram illustration of a British Boulton Paul Defiant interceptor fighter aircraft.
Description: Rendered on a deep dark background, this artwork presents Watt's flyball governor, its spinning balls rising with speed to regulate the engine, above the definition of the watt, 1 W = 1 J/s. James Watt (1736–1819) transformed the steam engine with the separate condenser and adopted the centrifugal governor to control its speed automatically. The unit of power, the watt, is named after him. Made for engineers, inventors and anyone who loves to understand how things work, it suits a workshop, office or study.
