As ARC is down, to follow up the thread Jim started there! Did a bit of research on this one!
FK105 is a typo in the AB book, other sources give it as FK115 - A Maurader 1 (or 1A - sources differ at present) - Baugher* lists it as a B-26A-1, serial 43-7391. It is listed as being with 45 Gp Comms Squadron from July 42 until it became 231 Sqn in Sept 44, then with that unit until July 45 (which also matches with it's disposal date on the)
As for Jim's belief it was a II, some mk Is (and certainly the MKIAs) seem to have been fitted with the enlarged intakes, and if it was being used for that length of time, a retro-fit is not out the question (Witness the ETPS B-25G retrofitted with a glass nose)
