I have a bottle of Dewars from the mid 1800's. The cork, cap, lable,bottle and box are all in excellent condition. Aprox date is 1860's. The box is made of a paper mache product and is tan in colour. Any feedback would be great. I have a bottle of Dawsons from the 1800's, with cap,lable and seal, but it leaks when tipped. No box with this one. I live in British Columbia, Canada. I would like to sell these items but I need some more info from experts like yourselves.
