 The following information and photographs have been donated to the Radio Officers' Association website, the donor wishes to remain anomynous at this
time. We respect his wishes and convey our gratitude for his generosity.

This particular MCR1 suitcase transceiver was operational during the years 1944/45 by a then young lady, who is in her 90's and still reads morse! It
was her personal equipment when she was a serving member of the British
S.O.E in Norway. When she moved from safe house to another location she
moved without the set. This was delivered later, usually again by a young
female with a baby in a pram. The set was wrapped in soiled nappies, and
placed in the bottom of the pram. The pram was inspected at checkpoints,
but they were  not interested in inspecting dirty nappies, so the MCR1 was
thus delivered to the next safe house.

The MCR1 was used extensively in WWII, and had quite a history in the
Far East and Europe.

The following two photographs are the operating instructions, for their
age are in extremely good condition.

 

 

 

 

 

 

 

 

 

The photograph above shows the MCR1, this is the original case. The
dimensions of the suitcase were 3.5 inches x 2.0 inches x 8.5 inches and
the weight 2lbs. The power supply voltages were between 97 - 115 and
221 - 250 volts. It was also run from a battery source.
