Age of Dewar's Bottle?
Looking for any information regarding the age of this bottle of Dewar's? The seller I purchased it from on eBay indicated that it was bottled for Romano's, a restaurant in Glasgow, in the 1940s. The bottle in sealed with a driven cork and foil seal (with 8-pointed star), and has a number "11" toward the bottom. In addition, the following markings appear on the bottom of the bottle:
G B C
C 25 C
Curiously, the font and some of the text appears similar to old bottles of Dewar's "Ne Plus Ultra" (see comparison photos in the following thread).
As always, any help would be greatly appreciated!
