Ahhhh... so you're the fella who wound up with these...
These are Mitchells from the 321st BG... probably all from the 447th BS, as the unit markings shown in a couple photos are that of the 447th and the named birds appear on
THIS webpage from
THIS 321st BG website.
Unit markings for squadrons of the 321st were roman numerals carried on the tail:
445th BS - 'I'
446th BS - 'II'
447th BS - 'III'
448th BS - 'IV'
Red fin tips were a group marking, although some photos I've seen appear to show different colors. This could be due to different paints and/or weathering, though.
The 'white' outline from the missing gun packs on 'Ruptured Duck' is probably actually natural metal, or maybe an underlying primer color.
Thanks for posting these!
