Do these guy's look familiar?

Do the names " Barr" or "Carlson", ring a bell with anyone? The first picture that's the names my dad wrote under it in scrapbook. The second picture is of my dad- "James Miller". The third picture is of Admiral Calhoun's plane at Bougainville for some work.My dad worked on a lot of planes . I have more pictures of the planes and some of the natives, including "Miss Bougainville" I will post later in a new thread. -thank you , son of WW2 veteran
