These images came from Richard Bauz of Switzerland [ has the Fb name Sand Mandli ] He owns the " Orchid Special " that Keith Yeates / Yeats ** built around 1969-61 [ a bit of a story there ] and raced in the 1960's
Keith's surname spelt both as Yeats and YeatEs ..
Programme Cover NSCC meeting December 1966 and some entry lists which show Keith was an NSCC member and entered under that club.
Think this is the entry list from the December 1966 programme
Other entry lists with the Orchid under NSCC entry by Keith Yeates / Yeats. **
See Trevor Sheffield and his Daimler SP250 #215 in the last three entry lists - appear to be from the same meeting.
