Hatfield Instruments Decade Resistance Box
I spend, as many know, a lot of to much time on ebay, where I found this decade resistance box made by Hatfield Instruments Ltd.
Well there is not much to say about it: 0–9,999kΩ, not overly accurate but made in manual labor:
These are lovely small devices, far more convenient than most resistance boxes. I have a couple of Rs and a couple of Cs.
