D model began to reach Europe in March 1944....
"44-13630, Special Project No. 92741-N, departed the US on 15 June 1944 and was issued to the 4th FG on 26 June 1944 where is served as VF-R “Rebel” with Joe Joiner before being reassigned to Melvin Dickey as “Betty Jane II”, also VF-R. It was subsequently transferred to the 339th FG where it seemed to spend a very short time as 6N-F “Honey” before being transferred again, this time to the 355th FG. With the 355th it was coded WR-M. Initially assigned to Clarence Graham as “Darlin’ Doris” it was reassigned to Albert Zimmerman as “Pittsburgh Smoker”. Zimmerman was the pilot involved in the 2 November incident when he suffered mechanical failure and bellied-in near Voorthoszen, Netherlands."
I also think it will be a similar model to the initial D
