A quick search of an internal database of Canadian airmen of the First World War held by the National Archives of Canada showed Salter Charles Askin as a pilot with 204 Squadron from 1 August 1918. This database had been converted from cards held by the Directorate of History and Heritage, DND, which were themselves probably produced from the Registers now in Air 76 at the Public Record Office in England. S.C. Askin was shot down and made prisoner of war, 12 August 1918. He had joined the Royal Flying Corps, 27 August 1917, from the Canadian Expeditionary Force. The database gives his birth date as 14 September 1898 and his town of origin as Windsor, Ontario. He was a student before enlisting.
For Canadian airmen who were transfers from the CEF, it is possible to search their CEF personnel file at the National Archives of Canada: (
http://www.archives.ca) A copy of S.C. Askin's file (RG 150, Acc. 1992-93/166 Box 273, File 31) can be ordered from the Archives at a nominal cost. The ArchiviaNet search tool to the CEF on the site includes copies of the front and back of Askin's original Attestation Form for the CEF, and this can be download. His birth date is given here as 14 September 1899. He had enlisted in March 1916 at Fort William, Ontario. His mother's address, Emily Askin, 59 Church Street, Windsor, Ontario is also given.
I trust this additional information will prove helpful.
