Telephone Sets "F" High Power No.1 MkII

[Bruce MacMillan]

TMC was a British company that manufactured telephones and telephone parts. They provided a lot of bakelite bits like handsets, etc to other companies/countries.

The 21 in the NSN indicates it was made in Canada. There were a few other companies that made phones like Stromberg Carlson and Dominion Telephone Manufacturing. I was still installing Stromberg stuff for BC Tel in the mid 1970s.

It was for HQ use and not forward positions. The regular type F (and others) could experience a lot of loss in certain conditions like high rainfall. The wire used was prone to losses. The high power set insured the boss could be heard.
