OK, here's another one for the esteemed collectors of ancient glowing devices.
This is a small metal case with latch. It's painted the post-war Navy gray. But there's no markings on it or anything inside it--of any kind--no military markings, no MFR logo--nothing. Open it up and there's five adapters on the left--obviously for some piece of test gear--and about 14 precision resistors in troughs designed to hold them on the right. The resistors are marked with their values which are all even--5K, 150K, etc. These resistors are in very small, square bakelite packages with 2 thin pins coming out the bottom--so that they almost look like miniature FT-243 crystals. The five adapters are distinguished by the odd pin arrangement. Each one has on the bottom one banana plug and 2 of the thin pins like on the resistors mentioned above. The 3 pins are spaced in a triangle about equidistant from one another on the bottom of the adpater. Each adapter is approximately a 2 inch bakelite cube. The top of each of the five adapters is different. One has an octal socket. Another has 3 banana jacks. And 3 of them have potentiometers with small knobs. One is marked 5K, another is marked 500K, etc. I have pictures of the whole shebang if anyone wants to try their hand at recognizing this thing. It's obviously some sort of precision test set accessory set--but for what, I have no idea. And the lack of any words, logos, part numbers, or makings other than resistance values is most puzzling.
