Radar Trailer

[hanesterry]

Hi Tony: I recognize the trailer you show in your photo as a ZPI (Zone Position Indicator) later known I believe as AA No. 4 Mk. 1 . I was a technician in the Canadian Army during WW II and worked on these units along with their companion trailer the APF's (Accurate position Finders). Together they made up the GL Mk 3C anit-aircraft radar.

I worked on these units in Canada and Australia where I was attached to the Australian Army along with 72 other officers, warrant officers and senior NCO's. We had to tropicalize the sets as they had not been designed to withstand tropical conditions. I believe some were installed around the Australian coast but they did not see action.

One was taken to New Guinea but was not installed.

Where did you get this empty shell and what are you going to do with it? I have the same picture of the group of units. I wonder how we both got it? Those trucks are not the FWD's but are the Chev cable trucks which were part of the convoy .They were known as "Gutless wonders" as they were underpowered.

I attach a pic of the ZPI with the antenna raised.

I cannot seem to attach more than one photo but I have others which I will attach to an ordinary e-mail if you like. what is your E-mail address? Mine is <hanesjt@sympatico.ca>
