Well I got an email from JoJo re your question. I speak of the bottle of Park Lane marked 1947 you have. Mmmmmmmmmmm well price is anyone who wants it that badly. Corby products were made at the Corby Distillery in Corbyville Ontario, Canada (Later known as the J.P. Wiser Distillery). The bottle in question bottled in 1947. If in original box, seal not cracked, bottle not cracked and the contents are clear and not cloudy than you have a thing of beauty. A bottle of PL 1958 went for around 93.00cdn so a 1947 depending on persons and if you deside to auction could run from 75.00 to 125.00 cdn.
So you have a choice enjoy a very nice whiskey that is still good as the day it was bottled or try an auction.
Now as for Thomas Adams stay touned I'll look into it for you. And Thank you JoJo.
