A while back we changed a service in an old house. The house had a bunch of cloth covered cable where the hot an neutral were #14 and the grounding conductor was #16. With everything going on we didn’t realize that the ground bar was only good for #14 through #4. Would you go back and splice #14 bare to the #16 grounds, or would you leave it alone?
 
I would leave it alone but I'm not saying that is the right thing to do.
 
Even if the hot and neutral were #12 and the ground was #16 I could pigtail the ground with #14 to the bar, correct?

I think your talking about the service bus grounding bar and old knob and tube wiring which often did not include a EGC ground wires but in your case 16 AWG.

CURRENT CODE is limitex to 14 AWG

SINCE this wiring was proably done before current code, i think you could have just pigtailed a 14 awg in the service panel onto the 16 Awg and terminate in the ground neutral bus bar

He stated that he has old NM cable no mention of knob and tube which did not have any EGC.
