Guy,
If you need assistance with an appraisal of your White Horse, please contact me directly at
wchurst@hotmail.com, and I will help you out.
I have been a Vintage Spirits Appraiser for several years, and have a focus on pre-1960's Whisky & Rum.
If you look around the whisky.com boards at bit, you will see quite a number of my responses on datings & valuations (particularly for White Horse).
I am myself a collector, and have about 40+ bottles of White horse in my private collection....I'll drop you a direct email shortly also.
Cheers,
Walter C Hurst
