Those peskey headsets for sale

[Chris Suslowicz]

Hi,

The manuals you actually need are these two:

SIG016 Signal Training Volume III, Pamphlet No. 22, Telephone Sets D Mk V, 1939
SIG017 Signal Training Volume III, Pamphlet No. 26, Switchboards U.C. 10-Line, and 6-Line, May 1940

which contain all the working, maintenance, and testing instructions.

There's also a later pamphlet that is just the list of components
that make up the complete equipment - this is of less use:

311 Switch Board, UC, 10 Line, Mk II Complete Equipment Schedule, Service Edition No. 42410, Complete Station, Simple Equipment, Oct 1960

Hope this is some help,

Chris. (Recently imported a 10-line UC from Canada but the idiot put it in a thin-walled cardboard box with no padding and it was dropped (as expected) cracking the operator and 3 line units in half (as well as other damage). I'm looking for spares and accessories plus a 6-line UC switchboard....)
