General radio 1432-m 5-decade resistor substitution box
GenRad 1432-M 5-Decade Resistor Substitution Box
Five decades, from 1 Ohm per step thru 10K Ohms per step. This is effectively any value from 0 to 100K plus in one Ohm steps. Physically, everything is fine with this box, and electrically too. I set the switches all to 5 with the results in the picture. Pretty respectable, and almost certainly individually more accurate than the cumulative error of 5 decades might seem to indicate. The only real issue with this box is that the cosmetics are a bit iffy. Nothing to really be worried about, but not necessarily a pretty box. Every bit as solid as you expect a GR box to be, though. Good bananas, all feet present - you know, a good box.
