This is one item of new, quad gang, carbon track pot. 

The shaft is the standard 6mm T18 splined type. The total shaft length is 20mm where 7mm is the threaded part and 13mm is the turning part. The splined section of the turning part is 10mm long. I measure the body width as 9.6mm and the body height as 11.4mm. The height including the pins is 15mm. The body length is 17mm. The mounting hole required is 7mm and a nut and washer are provided. The manufacturer is Bourns.

You might use a log taper quad gang pot as a replacement for a scratchy pot in your old quadraphonic amplifier, or as a first order Ambisonic B-format overall gain control in something like this:
