Hi Moose2,
This link,
http://rcafassociation.ca/uploads/airforce/2009/07/canrafa-d.htmlhas this information:
ABBOTT, F/O Lyman Carl (155130) - Croix de Guerre with Gold Star - awarded with effect from 21 October 1946. Directorate of History and Heritage document 79/201 lists him as a Newfoundlander in the RAF; enlisted 7 January 1941 (number 798644); demobilized 9 November 1945. G.W.L. Nicholson, More Fighting Newfoundlanders (St.John's, published by the government of Newfoundland in 1969) states (pp.444-445) that Abbott was a navigator in a Halifax shot down over France in the summer of 1944 and evaded capture. He had earlier flown bombers in the Mediterranean theatre. A search through London Gazettes from 1944 to the end of 1948 has failed to turn up his name or the date of the award. However, RAF Personnel Management Agency, in letter to H.A. Halliday dated 24 July 2000, confirms the award and effective date.
Hope this helps somewhat.
