Soundcraft broadcast console knob

These were from a couple of Broadcast desks and panels they may have been used on other mixers but I have not seen them yet

17.38mm high 13.87mm wide at the skirt 10.95mm at the top not sure diameter of the pots but looks small , insert looks like a bat maybe for a 4mm d

I have for now 4 colours

I found in the box where i was listing these a small bag of adapters which I presume (though not certain) go under the knobs maybe too space them correctly so I have listed them here
