The 7006 was a basic low-cost version of the BPO Telephone No. 706 made by STC. It is believed that these STC 7006 telephones were also resold by Modern Telephones Ltd. Modern Telephones had a deal with STC to sell PO-approved PABXs made by STC.
Almost identical to the Tele. 706, it had a resistor network in place of the induction coil and a self contained microswitch/hookswitch.
Probably just used on PAX systems.
The CAT 7007 model had a recall switch and 4 wire line cord fitted.
Two-tone grey is the only colour seen.
Ericsson's N1900E244 was similar.
