1880's Bottle of Claymore - help

[docky57]

Aquired this bottle as part of a debt. Dark green handmade bottle, looks like made from 2 halves. Stands 26 cm tall and filled to within 10 mm from neck. No evidence of there ever being a label. The stopper is embossed leather with claymore in a scroll above the crossed swords,underneath that "scotch whisky" and then Greenlees Brothers. On the top is embossed "Greenlees Brothers London and Glasgow - Distillers - Argylshire. The bottle has no markings except N or Z on the base. Done a bit of research 1883-1887 can anyone help me with more accurate dating or a value? [/img]
