Peterman and MASH

To those who provided the information that Peterman is not played by the same actor who played Col. Flagg in MASH, thank you. It had seemed to me that the young Col. Flagg, seen in a much older show, (and exhibiting some of the personality traits of Peterman) might have been the same actor, now older and playing Peterman. Apparently I was wrong, and I appreciate being brought up to date. Ariosa
