Sure - I can help you with that....I have a large data-base of White Horse information, as well as fairly large collection of my own.
If you would like additional information on your bottle, please forward some clear photos of the Front-label, Cap area, and Back of the bottle to me, and I will get you a dating on the bottle within 24-28 hrs.
Cheers,
Walter C Hurst
