Whatever the GE rig is, it's not a Master II. I suspect you have some 
form of a Master Progress Line, if it is all tube. (which it appears) 
Based on the Mic, it's Progline to Master Pro vintage. The chassis 
construction looks like Prog Line.

Progress Line- (Prog Line) All tube, could be vibrator or solid state 
chopper mobile Power Supply, or Base with diodes
Transistor Prog Line (TPL)-  Neat modular  hybrid mobile, solid state  
RX and  TX  except for  PA.
Master Pro- Solid State receiver, Tube final
Master Exec- (Exec)Solid State
Master II- All solid state, "modern" non-trunking. (Late 70's through 
early 90's)
Master Exec II (Exec II)- All solid state, slightly lower duty cycle on 
base/repeaters, different package than Master II, but many of the same 
modules. PA and xtal accuracy main difference

I used Prog lines as mobiles and base for 2m use in the 70's, TPL for 
mobile, and Exec II's, Mstr II's, and MVP's as repeaters. All are great 
radios!

Have fun!
