Hello Alex,
thanks for your answer.
The 23/12/44 kill of Jones: I think you're right about it being scored is a Beau because the website indicates the first P-61 kill by 414 NFS was scored on 4/2/45. Andrew Thomas and Warren Thompson write that this unit scored 13 kills (of these five in the P-61). The Lutz kill you described fits in well if we assume that Clark's 26/11/43 kill and Anderson's 23/01/44 kill were half-shares with another unit, respectively.
Could you agree ?
Walter Groom and Harold Roth: all I can say that they must've existed.
