This S.O.E. (special operations executive) set is still admired by today 's experts
for its 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 tubes 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.
