Chorley adds in his Vol.4, Additions and Amendments to Previous Volumes, page 490:
Sgt (Obs) Paul H. MOREY (916057) and Sgt (Pilot) Lindsay R. WILLIAMS (RAAF 402429) to the casualties of Wellington III X3599 of 57 Sqn.
However, in my files both airmen are already listed as casualties on Liberator II AL577 of 108 Sqn. (Lindsay confirmed AL577 on National Australian Archives).
What is correct ?
