Beswick Swish-tail Palomino Horse in high gloss.
Designed by Arthur Greddington. Model number 1187
Here are photos from eBay of the rare Palomino Horse sculpture. I am lucky enough to own one of these. More pictures are shown below.
The Palomino is one version of the Swish-tail Horses. I also have Model number 976, the Bay coloured Mare in gloss, looking left.
