The Royal Braemar Gathering, Braemar old postcard 1950s/60s

Apart from one or two obvious cars I can't begin to guess what most of these are, so suggestions welcome. Possibly a blue Bristol in there?

 

I think it's a 1950s photo rather than '60s, as there are no Minis, BMC Farinas or Anglia 105Es to be seen.
