also the single P-47 MACR for that date details a P-47 lost in New Guinea.

Maybe Eder's claim actually was a P-51:
4671 P-51 42-106682 4 334 Barden Lt. John L POW near Liebenrode
4434 P-51 43-12383 354 355 2/Lt. Paul W. Kallas KIA near Goedekkenrode
4422 P-51 43-6424 354 353 Capt. James (NMI) Cannon Kleinleidingen/Grossgleidingen

or maybe (have no crash data):
4224 F-5 42-13124 5
4799 P-38 42-67007 51
4510 P-38 42-66985 51
4406 P-38 42-67447 364 384
4407 P-38 42-67438 364 384
4408 P-38 42-67417 364 384
