Yamaha Allen heath Behringer Soundcraft odd Knobs fader caps pack of 4

I have tons and tons of odd mixer knobs or some people say caps or push buttons ,

So as I find them I will add them here, all are in a pack of four as this is the only way to list them, Main Soundcraft knobs are listed elsewhere but later on they used these cheaper types

Please note the "Tang" is the bit that sticks up and the knob presses on, i have measured the middle of knob to end of Tang hole, some knobs are level some the Tang hole sticks out a bit if that makes sense

I have the following types now and will add more later, if I know exactly the model they will be listed under model number everything else goes here

Blue 27mm x 16mm x 7mm for 8mm Tang ( Tang sticks out 2mm) S1397

Dark Grey 27mm x 10.9mm x 9.9mm for 8mm Tang (Tang sticks out 3mm) S1398

Light Grey 24mm x 10.9mm x 8mm for 4mm Tang (Tang stick out 2.4mm) S1399
