I need the manual or schematic of the General Radio model 1109A (military 
version was OS-16/URM-18) comparison oscilloscope.  It is a three inch rack 
mounted oscilloscope with a circular display for timing measurements.  It 
uses a type 3DP1 cathode ray tube.  Also looking for the manual to an 1190 
oscillator.

Thanks,
