More information for you.
Your Canadian Masterpiece is in Exc. condition from what I can see. Many speculate that Canadian Masterpiece was the forerunner of Crown Royal. I had a chance back in the early 90's to try some CM and I would say it is much like Crown Royal. It is again if clear as it looks drinkable and as to value between $40.00 $50.00 at auction.
Now the Japanese Santory Whisky..... I've never had before and is a nice bottle but one of those things from Japan that is not worth alot. If clear drink it at a get together and keep the bottle. A Bottle went on a Japanese Auction for $17.00 CDN But all I have for this one.
As to the Shenley the imported OFC 12yr old marked 1949 I would like to see more pics please.
