Bottle is much later than the battle so a commutative piece circa 1760. On the back is a painted crest - with a lion and shield with decorative scrolls and plant leafs painted in gold. Bottle has a string lip, open pontil and stands 12 5/8 tall and at the widest point it is approximately 10 1/2 diameter and at the base 7 in diameter.
The paint on the front is worn in areas across the portrait and battle across the front approximately 70% of the paint is in tact. The paint on the back is fully in tact but does show some ware. The bottle itself is in excellent condition shows normal ware on the bottom that is consistent with its age. This is an amazing piece.
