1235 and 235 are the same aircraft, which went by these two designations while in service. These two should be linked but adding the name "Dragonfly" to 235 - everything else looks the same.
N4927E is the FAA registration carried for a while but linking this caused some extra profiles to be generated. Since the FAA link is a common problem, we can delink that and then just make a comment on the military profiles.
