This is a very nice brown gloss example of the Beswick Mare(Facing right,head up)Model 1991 .Designed by Arthur Gredington.
I can tell it's a 1st version because  only the end of the tail is attached to the hock.In the 2nd version the tail is attached to the quarters and hock.
This was introduced in 1965.End date of production is unknown.
These early versions have superb shading and muscle definition...this is in excellent vintage condition and a great example of this early model.Defo one for you collectors out there!
