heathkit resistor 'decade box'
a nice old one, in a wooden box. not sure how old it is. could be older than I am (oh my!).
looking around on the web, models like this were sold from 1949 thru 1951.
I cleaned it up (inside and out), replaced the banana jacks with new 'gold' ones, (knobs are still original, from what I can tell). I added some cherry stain and now its in quite usable and presentable shape.
there are some red wirewound precision resistors inside and while its not 'lab accurate' its a great substitution box or even 'transfer standard' for arbitrary resistances. just not always the ones that are literally marked on the dials, lol.
