There are two profiles for N34, with the bottom one linked to N64766. I have been unable to locate any information which shows N64766 ever carried the call sign N34.
I've read the history of N34 and it appears to have carried that registration from the time it was acquired from the Navy. I don't know where the other N34 profile came from. If there is no evidence that N64766 was ever registered as N34, I suggest the profile be deleted.
I was researching this because I have photos taken from 1985 and 1988 of N34 and I was trying to figure out which profile it should go to.
