White large Fader cap push button 26mm x 14.8mm 7mm Tang marked 38 pack of 10

I had a lad in the UK ship me a whole pile of different caps and pots etc

In the box there was 2 huge bags of these caps that I think maybe have been used in Soundtracs stuff but I am not sure.

These are marked "38"

But If you need these you can turn these upside down then you do not see the 38
