Based on the fact this states it was distilled, matured, and bottled in bond by Irish distillers Ltd Bow street distillery I would say this bottling is from the early 2000s as in 1986 the brand was purchased from Gilbeys and in the 90s it was Fitzgerald & Co who looked after the Redbreast brand. It bears the description 'Pure Pot Still' which was changed on Redbreast to 'Single Pot Still' in 2010.
