Hello all.
"Butt" is an abbreviation for it's correct name Buttinski.
A butt is a works type of phone used by both external plant linesmen as well as telephone exchange technicians and customer premises equipment installers.
A butt can only work on CB (common battery) or automatic phone systems.
A bag set is a larger field or linesman only type of works phone such as the Plessey N1845F. This phone can work on magneto, CB and auto phone circuits.
The bag set was popular amongst PMG employees in Australia as it was quite rugged in construction, worked well and the shoulder strap was convenient to hang the phone from a crossarm on a telephone pole.
Cheers, Robert.
