[AMRadio] Early and Military Super-Pros

[Merz Donald S]

Question: Is there a definitive guide somewhere to the early and military Hammarlund Super Pros? How do you tell the different models apart? What is the military equivalent of an SP-200? Or vice-versa: what is the civilian equivalent of a BC-778? Does the color of the front panel mean anything?--black? gray? Which RA-whatever power supplies go with which military models? And (while I'm at it), why the hell is the knob shaft ALWAYS broken on the phasing control?

Documentation? Does anyone have any manual copies for these radios for sale?
