Vintage CTS 25K Long Shaft Potentiometers For Amps. I think they are from the late 60's early 70's taken from a  a could of clubman amps.

1/4 notched shaft

I have other parts such as switches and knobs, I also have 2 x 5k CTS pots of the same sort and one 1k CTS pot.

I only ship to the UK mainland not northern Ireland, sorry
