Hello Mark,
according to my data, Frosty Moller was converted into an auxiliary netlayer (XAN) and was sunk by US air attack 26/11/43 in Ceihang (or Chianghai) Bay, Canton, 21.33 N, 112.00 E.
Raids by the 14th USAAF that day included 2 B-25s attacking a "freighter" in "Honghai Bay", which seems to be the best candidate for this sinking, the remainder of the attacks being made by P.40s in the Chang-teh and Te-shan areas.

(The Sabres are still going strong, I'm rooting for Teppo to score against Atlanta tonight)

Regards, Brian
