BID - 50 Portex |
The Canadian Army used the Portex system in the early 1960's but it is not known how long it remained in service.
With top cover in the up position. This is the front panel of the Portex with BID/50/1 nameplate visible. Carrying handles unfolded. Various vews of the Portex. (All photos in this table by John Alexander, G7GCK Leicester, England.
The green coloured Portex displayed at the Royal Signals Museum appears to be a later version of the black coloured Portex. There is a series of pushbuttons above the rotor slots. Does anyone know the purpose of these pushbuttons? Contact : jerry.proc@sympatico.ca)
