Vintage Tremolo pedal / footswitch - valve amp - combo early 1970’s simms watts WEM vox Selmer

Here we have an early seventies tremolo on off pedal 

looks to have been a Simms Watts one originally but it 100% sure

will work with loads of amplifiers, Selmer, Vox, Carlsbro etc etc although you may have to wire a different connector if using this with a WEM as they used a phono connector

can also be used as a reverb on off switch, 

fully functional with a decent length of lead 

any other questions just ask
