Replacement 3 port foot pedal for the Alfamacchine / Minigraf 3, 4, Cassese Cs89, Cs20 and later versions of Cs299 underpinners, '3 port' signifies how many pipes are connected to the rear of the pedal.
Info: Cassese before their demise started cost cutting by fitting the cheap & very nasty EMC branded pedals, our pedals are made by Pneumax and are of far superior quality.
