You have no doubt heard from Delia Palmer re Roy Ellis, a stoker from 357. Apologies if I'm repeating myself here, so many things going round n round n round in my head at present.
I have also tracked down David Moore here in Oz (Sydney) who as young SubLT, RANVR served on 357 from 7 Jan to 26 Feb 1943 and again 3 May to 16 Dec 1943. David's claim to fame is that he had the top of his scalp slightly parted by a bullet as they came into Castellorizo in Sept 1943.
I am also awaiting an e-mail from the CFHT regarding a David Lloyd, also here in Oz who's father the late Kenneth Lloyd DSC while not having served on 357, was on ML 356 another 42nd flotilla ship.
