N12 #13a. This is not a mis-placed photo in the Hs instead of the Ms. It is thought that this was probably HOME WRECKER and would have been attended by female artwork. It's 7BG and a FORD but that's all that is known.
N12 #15 HONEY WAGON - a well-used B-24D which makes it all the more unusual that it is unknown
N12 #16 HOOMALIMALI, 308BG
N12 #17 HOT BOX. The name obviously temporary abd the significance of the artwork is unknown
N12 #18 HOT BUDDY, suggested as 90BG
N12 #19 HOT ROD, 15AF
N12 #20 HOT STUFF, 44BG
N12 #21 HOT TO GO lists as 307BG but I doubt it. More likely 7BG
N12 #23 HOWE'S ABOUT IT. The other images here don't appear to offer any clues: WHTE ANGEL is a CBI C-109, the tangled wreckage could be anything anywhere and the wreckers could be 9th or 12th Air Force.
