Hello and Good Morning Spaniard.....
You stated:
"Canadian Scouts,aka Howard's Scouts (Record Group 9, II-A-2, volume 340, file 20142).
No service files have been located for those who served with scout units."
From the Regimental History of the Canadian Scouts, "Knowing No Fear", the author states:
"The National Archives at Kew in Britain holds some records for the Canadian Scouts, including Medal Roll, Nominal Roll and some Enrolment Forms. These records though incomplete, provide considerable information. For personal experiences, the best source was letters, found in family records or local newspapers. The quality of the records varied considerably and many contained inaccuracies which have been resolved where possible. It appears that only two former members, Sergeant Jack Randell and Trooper Frederick Raper, wrote autobiographies. Jack Randell's work is flawed by his tendency to exaggerate and Raper's book is unfortunately lacking in detail. This is balanced by some extent, by other documentation (Note: There is a very extensive bibliography), such as clear and concise notes left by Sergeant William Babty and the letters of Sergeant Singleton Muncy and Lieutenant Robert Ryan. More recently, Neil Speed in Australia wrote a biography of Charles Ross, "Born to Fight", including his service in the Canadian Scouts.....
By the same author as above is a book called "No Colours No Drums the History of the Canadians in the South African Constabulary" where he went through and copied all the Canadian SAC documents in Pretoria.....
