I have the data below. The date of 03Nov43 would be the CAT.E FA date recorded on the Movement Card.....
FP120 Catalina IB (c/n 707) accepted 05Jun42; delivered 20Jun42; Elizabeth City; ferried Gander Lake to SAL, Greenock 09/10Sep42; 4 (C)OTU Invergordon 04Oct42; 4 (C)OTU Greenock 20Mar43 [hull code F]; 4 (C)OTU Invergordon 21Apr43; 4 (C)OTU Greenock 16Aug43; RAF Greenock 22Aug43; 4 (C)OTU Alness 08Sep43; 131 OTU (no date); 131 OTU Cat.E FA 03Nov43 after going missing on training flight. Last known position near Malinmore Head, Co. Donegal, NI. Nine crew lost; SOC 30Nov43
While the AM78 cards are important I would hesitate to treat them as Gospel.
Geoffrey has already pointed out the origin of the photo (IWM) where they state it went to Egypt and served with the 70OTU at Shandur This unit is known to have operated the Baltimore. Jim Halley in his book (as does Andy Thomas) state the aircraft was used by the 454 RAAF Sq also based in Egypt at the time.
This leaves three pretty good authorities (none of which are Gospels either) that have to be wrong while the AM78 has to be right.
While the AM78 cards are both good and solid when it comes to aircraft which stayed in UK they falter heavily when it comes to aircraft transferred to North Africa/Middle and Far East.
If I am not mistaken, historians can only rely on the remaining ORBs and log books including photos to determine at least a roughly such aircraft's histories so far from home.
I agree it is odd there is no mentioning of the aircraft being either shipped out or TOC again when returned. I was pretty certain myself it had been shipped out but is more hesitant now after a very lengthy discussion on AB-IX. Would be interesting to see if anyone outside AB-IX can solve our riddle....
