From the Scotsman, 4 March 1933:
Glasgow Headmasters
Glasgow Corporation Education Committee yesterday approved the appointments of the following headmasters:
....Scotstoun School, William Malcolm, M.A., (Yoker School).
I would guess that he was leaving Yoker School for Scotstoun School, from the way the rest of the entries are written up.
Something to work on to check what records there may be
