This S.O.E. (special
operations executive) set is still admired by today 's experts
design, workmanship and for its technical performance.
It easily handled regular communications over more than 500 miles.
Its receiver was
particularly sensitive and stable.
The A Mk3 was the smallest
transceiver conceived during World War II.
It was completely
miniaturized except for the" lock-in" American tubes.

The Type A Mk III was the last step before the creation of sets
with valves the size of peanuts.
Transistors would not appear until several
years after the end of hostilities.
The new radio procedure, separating
transmission and reception in time and space,
permitted the creation of
these miniaturized sets which were used in the last part of the war.
