If you take a large sample of 20% resistors, most of them will be more than

before labelling.



Allan-Bradley (Speer) carbon composition resistors such as these are
standard low-temp indicators. When production was cancelled (in the
late 60¹s or early 70¹s) the low-temp research community formed a
consortium to buy up the final weeks production run of the most
favored values.

Any decent low-temp lab will have a secret stash of these babies on hand.



Most modern resistors are in the range of +/- 2% but are usually marked as 5%.
