I own Quite a large collection of fountain pens among which about 5 "Targa's" Just like you I restore old pens and polish bad writing nibs to make them write smooth. I can assure you that cleaning them in an ultrasonic cleaner does not effect the nib in any other way than by letting it come out clean. Did it dozens of times with my pens whenever they seam clogged.
