Johnnie Walker Red Label Vintage bottle - look for valuation

[PerekB]

Hi, I just acquired an old Johnnie Walker red label 1.75L bottle, sealed in its original carton box (never opened).
My grandparents brought it from abroad in the 60's I believe (there's no date on the box), and I'm trying to see if it's worth anything segnificant.
Thanks for your help.



edit: here's a phote I found online of an openned version:

Is it similar to this bottle

If not have a look through mctears auctions they may have one similar to yours and it will give you an idea of value

I guess it's similar, but while this one is 26 2/3 oz (0.75ml), mine is 59+ oz (1.75l), so the value should be higher. also, mine comes in the original box, unharmed, with a leather handle.
couldn't find it in the auction site, anyone else has an idea?
