F models, and neither of those posted are 44th BG. Top photo is a 305th BG B17F from the 8th AF named Southern Comfort.Bottom one is "All American" a 97th BG B17F, 12th AF in the MTO, that was hit by a 109 with a dead pilot, nearly severing the tail. A very famous WW2 photo btw.BTW the 44th BG was a B24 outfit. They also had a Southern Comfort.http://www.b24bestweb.com/southerncomfortiii2.htm
