The other day I dismantled an analogue multimeter, which I had built from a kit in the early sixties, and found these two diode half-bridges.
I'm wondering if they could be WW2 surplus?
Each diode reads about 1700 (when forward-biased) on the diode-test setting of my DMM. I'm guessing the half-bridge is constructed by centre-tapping a selenium-coated strip/rod. Thoughts?
