blended scotch and bourbon

[jason]

hello, i inherited two bottles of dewars and sons "ne plus ultra", one bottle of hedges and butler, one bottle of old rarity and a bottle of old fitzgerald bourbon whiskey. all seem much older than anything i can find on ebay to try to reference their age and value. can anyone shed some light on how i can find out. the dewars are in short square green bottles. the old rarity is in a short square clear bottle. hedges and butler is in a tall dark green bottle. and the old fitzgerald bourbon whiskey is 6yr and bottled in '71. any help is appreciated. thank you
