I must admit I don't know what the purpose of the original unit is. Perhaps as part of a bridge given the galvanometer connections. I know when I was looking to check out my HP 4284A precession LCR meter (basic uncertainty of 0.05%) I was able to buy some 0.005% resistors in some values. I think if trying to build a precision resistance box I would look for resistors better than the 0.03% in there. I wonder if you could go to much lower resistance values if you used the galvanometer connections as sense wires. But maybe you are using it in a way I don't understand. I only have my mobile phone now, so are not going to search the web for more information.
