I'm looking for 3 Underdog eps. Actually I'm looking for 3 McBragg shorts, but it's probably easier to pinpoint their whereabouts via the Underdog titles. I'm not absolutely sure the shorts are within these titles, but if anyone has the complete series and can check them, I'd be interested:

Underdog #67 "The Forget-Me-Net/Part 3"
Commander McBragg #34 "Dam Break"

Underdog #69 "*Whistler’s Father/Part 1"
Commander McBragg #35 "The Eclipse"

Underdog #95 "The Big Dipper/Part 3"
Commander McBragg #48 "The Orient Express"
