Teac A-2340SX and many others Front Knob dual or single

I have listed these on their own as people search like  this.

The dual one is pretty common on all of the later A-series but the single is not as far as I can see and is rare as others in this four track series often have a chrome top or smaller size

The big knob is 20mm high and 24mm wide at the skirt widest part

The dual just stacked on top of each other is 29mm high in practice it will be about 30mm as has to sit a bit proud

Price for 1
