Minifigure warhorse for medieval knight LEGO Alternative

warhorse, likely an accessory for a medieval knight minifigure, possibly from a faction using a white lion on a green field as its emblem.

The horse itself is brown. It is wearing a silver chanfron (head armor) with a prominent silver unicorn-like horn. The horse is covered with an ornate caparison (cloth covering):

• The main body of the caparison is green, with a white lion rampant (standing on its hind legs with forepaws raised) emblem on the flanks.
• The rear part of the caparison, covering the horse’s hindquarters, appears to be brown with a printed silver chainmail or scale mail pattern.
• A green saddle or seat area is also visible.
