A few clues:
Cruising through some race reports, with almost zero mention of Sprites, I learned that Hume Weir was hotmixed in stages during 1966.
Over reports from 1963 to 1966 I found mention of four TR3s, driver names being Thompson, Duckett (Lyndon?), Ian McNeill, Brian Gilles (specifically mentioned as TR3As) while it was said that there was a 'brace of Triumphs' in the way of quicker cars at one 1966 meeting.
Sprites were usually mentioned only as in groups, names which did emerge were Howard Hill, Geoff Watson, Linden Sampson and Joe Hlubecek.
It seems to me, however, that you could overcome a lot of this stuff by obtaining old programmes and result sheets. Surely, if you checked out old members of the ADCC you would find someone who kept all of these and could let you photocopy the entry list pages from them?
