This is one item of dual gang, linear taper, carbon track potentiometer.
These are new items and come with a nut and a washer for mounting on a front panel. The T18 splined shaft is 6mm diameter. The mounting hole required is 7mm diameter. The connection pins will allow either PCB mounting or soldered wire connections. The "B" prefix before the track resistance value denotes a linear track taper. The max power rating is 0.1W.
The length of the turning part of the shaft varies slightly between 8 and 10mm depending on the particular track resistance.
If you have a pot with a track label of B503, this is a B50K where 3 is the number of zeros after 50 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 e.g. 50KB.
