Dunglass was a single malt produced at Littlemill distillery from the mid 1950's through to 1968. Duncan Thomas, who owned the distillery, was in inventor and tried to produce different whiskies by various methods during this time, there was a third malt produced but I've forgotten the name. He also built Loch Lomond distillery in 1964.
The label states Barton Distillers who started as a partner in the 2 distilleries and ended up owning them after Duncan's death, so I would assume that the bottle comes from the mid 1960's to around 1971/72 when Barton **** both of them.
