set of 6 of NOS unused control knobs 

made by Bulgin in the 1960's these have some wear from storage but have never been used. 

These will fit a 1/4” shaft, the caps remove to tighten the knob on the shaft 

1-1/8" wide 1" tall

perfect if you have a amp with newer knobs, or if you want some vintage knobs to complete the look on your jtm45 clone, likewise if you have a new build and want some cool knobs 

anything else just ask
