Perhaps I can be of some help as I know some of the history of the area schools including Shaw Creek School at Nitinat. If you wish, I can try to contact a local senior citizen, a woman, who for many years taught at the school up until June 1972 and ask if she has a photo of the school. I am a local historian of the Cowichan Lake area so will also check at the local Kaatza Station museum to see if they possess a photo of the school or of the classes.
I can tell you that the student/class registers are no longer in existance as they are reported to have been lost many years ago. Is there a particular name you are searching for as I may be able to help you in that area as well? I do know that the school operated from 1937-1949. I have a written (very discriptive) history of the school but very little is written about it prior to 1957, when the name was changed to Nitinat School.
If you wish me to persue the information further please contact me at my email address at firstname.lastname@example.org
