Unfortunately none of the records of the RAAF crew are digitised, nor funnily enough is there a Roll of Honour circular about the crew.
Full names etc are given below, please note it's GADSTON for one of the gunners not Gadsen:
1868639 Sgt Samuel John Spooner RAF (flight engineer)from Kettering
1389429 Sgt William Edward Lynch RAF (bomb-aimer) from Leonard-on-Sea
423214 Sgt Edward Alan Bock RAAF (navigator) from Newcastle NSW
430256 F/Sgt Noel Wilkinson Gadston RAAF (gunner) from Kew Vic.
411099 F/Sgt Malcolm Douglas Moffatt RAAF (gunner) from Armidale NSW
423313 W/O Francis McLeod Percy RAAF (pilot) from West Maitland NSW
1119630 Sgt Fredrick Howard RAF (W/Op), no further details
The crash site is given as Hollenstein Germany whilst returning from a sortie to Brunswick.
