Today little is known about the so called
J Force sets other than that they existed. The "J Force" version of the ZC1 is
believed to be the last batch of ZC1's to be produced. Today it is
hard to determine exactly how these sets looked. We have been told by
one individual that a cord similar to the "Drop Lead" set was used but was
fitted in place of the regular headphone/microphone sockets. It
clear if these sets were manufactured like this or if they were standard
production sets which were modified as a batch after manufacture.
However, general opinion is that they were the last ZC1's down the
British High Command saw the ZC1, despite
its superior qualities, as outside the range of equipment considered to be
standard issue for British and Commonwealth Forces. With a growing
trend towards rationalisation of equipment to facilitate joint training, the
supply of common spares and the interchange of equipment between different
units forming part of joint operation forces the ZC1 was frowned on.
Senior Command believed the 19 Set was standard "Kit".
The J Force sets were produced to permit
the use of the standard 19 Set "Drop Lead" arrangement for Microphone and
Headset. It was hoped that this would make the modified sets
more acceptable by facilitating their fitting to vehicles already fitted out
for the 19 Set before allocation to NZ units serving in joint Forces.
The first post WW2 operation New Zealand was to be involved in was the
occupation forces in Japan, hence the name J Force ZC1's.
Today it is not known how many, if any, of
these sets saw service in Japan or elsewhere. Surviving members of J
Force spoken to only remember using the 19 Set. In the early 1960's a
number of new J Force ZC1's were offered for sale by companies such as
Valentines of Hamilton.
