This is one item of new, single gang, linear carbon track potentiometer in various resistance values. These are new items and come with a nut and a washer for mounting on a front panel.  The mounting hole required is 7mm diameter.

The shaft length on all resistance values of these pots is a total of 15mm, where the threaded part is 6mm long and the turning part is 9mm.  The plastic dust cap is not present on all track resistance types.

If you have a pot with a track label of B253, this is a B25K where 3 is the number of zeros after 25 in Ohms.  A 502 would be 5K, a 472 would be 4K7 etc.  Sometimes pots may also be labelled with the B as a suffix i.e. 25KB.
