B/W film from 1960's & 70's of Horse trotting for tapp, maybe John Tapp

Looks about 5 minutes total of highlights, no reel with one

They come from Channel 7's World Of Sport run by Ron Casey 

I would presume digital copies could be made for personal or archive use.

These are old films, so bare that in mind when bidding

I'll be listing a lot of film history for the same era and happy to combine to save on postage.
