Finally got down to this demonstration after a while. Featuring my exceptionally rare Simplex 4040-60, the precursor to the 4050-80, dated 1967. This demonstration involves both continuous and 60 BPM(ish) march time coding, featuring the 12 VAC 4040 that came with it. All is switched on a NIB Simplex 4251-111 Chevron pull station.
