A real museum piece - Dunville's was produced by Dunville & Co. at the Royal Irish Distillery in Belfast, which operated from the 1870s but closed in the 1930s, so this would have been some of the last stocks to be produced. A dram of Irish distilling history.
Please note this bottle has a low fill level as shown in the photograph.
Please note that this is an old bottle and the closure may have deteriorated; care should be taken when opening the bottle. As such, the item is sold as described.
