Brimar R18 Rectifier tube Pre production sample. Never used. Tested with AVO 160.
We received this valve from Brimar England, when I worked in Germany in Telefunken Ulm in the 1950's. We where supposed to test and then distribute them. But nothing came of it.
The valves came in a box of 10 units. This was the only one saved.
