[Milsurplus] CRT #'s

 Patrick's mention of a 1x3 CRT incited me to go extract the CRT from that
mystery G186B +ACI-spectrum display unit+ACI- s/n 19009.  It has a 3XP2 made by Waterman
that measures 1.5x3+ACI-, with an unusual (to me) loctal base.

Anybody know what a 'G186B' is for?  I can send an exhaustive description if
needed - briefly, it's an aircraft unit w/ HWD of 5.25x9x15+ADs- 10 nuvistors, 6 w/
caps, 4 w/o+ADs- The front panel has an +ACI-edge+ACI- lighted (three lamps in a central
triangle, actually) lucite overlay with these control legends cut into it:
Marker On/Off, Power On/Off, Sweep 5kc, 20kc, 50kc+ADs- Lin/Log, Center Freq., Gain.

I saved it 'cause the power xfrmr can be used to repair my RCA WO-33A o'scope
