I obtained these and more like them back around 1977 from a surplus shop outside Boston MA USA. They look like the sort you find in Japanese transistor radios, except these have both leads at one end. Usually, to mount an ordinary resistor vertically, you have to fold over one of the leads to run parallel to the resistor body to get back to the circuit board. The pictured resistors look to be a reasonable answer to this, don't know why these didn't become an industry standard. These resistors look to be made using ceramic tubes with resistive material on the outside (under the paint), and one of the leads passing through the tube center and terminating at the top, and the other lead terminated at the bottom dogbone resistor style as usual.

Interesting. Have never come across those before.

Never seen one myself but a good idea, especially where miniaturisation is the order of the day.

I remember seeing those in Japanese consumer devices back in the seventies.
I guess SMD put and end to all those different styles of passive components.
