we have  some  mk 4  indicators  used on a mk   37   gun director... was 
this a mark  4  radar   also>??
we  got an entire trailer  load of stuff  from calif   once and  I pulled 
one of the airborne radars to display but there   were many pieces of Navy  
ww2  radar...  there was this power  supply western electric  that even 2  
people had to   almost  die  when  dragging it... then there  were some of  
these indicators like this in the photo ...
 
This  stuff  has  been  stashed  for   years...  is there  manual online  
for this indicator or   does anyone have a file!? there is also a  chance  we 
have more of  these indicators than we will need to  show and tell in our   
expanding RADAR area.

I picked up this WWII Navy height-finding radar display unit recently.  Pix 
have been uploaded. This was part of the Mark 22 radar that was mounted  on 
a Mark 37 Gun Director on a ship in 1944. The display is an E-scope  
(elevation is the vertical axis, azimuth is the horizontal). I've seen the  
Western Electric operator's manual but it doesn't explain the colored bar  zones 
visible on the scope's reticle: red, then orange, then purple. Does  anyone 
have any background on this? Since the Mark 22 was primarily  concerned with 
low-flying enemy aircraft, my thought was that red indicated  that the 
target was too low to shoot effectively, orange was the sweet zone  & purple was 
to indicate that the target was too high to shoot. Good  chance that this 
unit was responsible for downing a kamikaze or two!
