WWI Vintage Dickel "Cascade"

Hello,

I was wondering if anyone could provide me with some information regarding my bottle (still full) of Cascade Whisky. I know the basics of Dickel, and his move to Louisville where this was bottled... but was wondering if anyone knew anything regarding value, if it's safe to drink, etc.

I know it was bottled during WWI because of a special label at the top apologizing for the use of a cork because the "European War" made it difficult to obtain caps.

As far as safety in drinking it, the cork does not appear to be the greatest... it has shrunk (or was bad to begin with) and barely hangs in the neck - is there a way to pull it back up without pushing it down or screwing into it? Also, there is some lees in the bottom (or at least that's what it's called with wine, but I didn't know Whisky did that - maybe it's cork debris?) is that safe? I've heard cork can go bad and cause some sort of infection, hence my apprehension.

However, I'd consider keeping it or selling it if there is any value... I heard WWI whisky bottles can go for a decent amount but I have no clue about these things.

Thanks for the help,
Kenny
