I remember Macks Golden Stepper,he was at Highlees Stud, Paddock Wood in Kent owned by Margaret Pocock, beautiful horse. I owned a half arab Highlees Tan Sensation whose sire was Lady Blunt's Arab stallion Salvador from Mayfield East Sussex, his dam was one of Mrs Pocock's palomino mares and he was from her first batch of foals but chestnut rather than palomino. Highlees Stud was top notch back in the 60s with indoor school and barn stabling, Margaret was Canadian, it was also a riding school
My Palomino's have Macks Golden Stepper in their pedigree. My first Palo Ishtar was by Snow Warning (TB) out of Highlees Bo-Peep who was by Macks Golden Stepper out of Be-Bop of Goldmount.
