Wing Pinion Tanks

These were the external fuel tanks sticking out of the wings of the de Havilland Comet. I was wondering where the name came from. And have there been any other aircraft with these kind of fuel tanks.

I have nevr heard the term "pinion tanks" before. The Lockheed Jet Star had "slipper" tanks and there was an after market slipper tank made for the Viscount. I don't think the Viscount mod was designed for airline use, but rather a corporate mod (STC), to increase range. The singer Ray Charles had them on his Viscount.

Not a great picture but you can see them protruding from the wing on these photos. These may have also been called Tenneco tanks as I believe they once owned this arcraft at paid for the design?

Seems pretty straight forward to me:
Noun (plural pinions)
  1. A wing.
  2. The joint of a bird's wing farthest from the body.
  3. Any of the outermost primary feathers on a bird's wing.

Flight magazine hedged its bets when featuring the Comet 3 in 1954, describing them as "pinion" (in quotes) tanks, suggesting that it had never encountered the term before:

I always knew of the later Comet 4 and 4C's front mounted wing fuel tanks noted as ''pinions''
I'm probably as old as Dave above though lol
