Lizmac, this is what we found out from the Diageo archive department...Your bottle of Buchanan's has been dated to be from the late 1960s – early 1970s. The Royal Warrant statement is ‘by appointment to the Queen’ which makes it post 1955. The front label is very similar to the examples the archive department has from the end of the 1960s, and the shape of the bottle and the closure are in keeping with the changes that were made to the bottle at the turn of this decade. Your bottle is an example of the product that is now Buchanan’s De Luxe 12 Year Old, which dates back to the 1920s in this format. The original Buchanan’s Blend was the company’s very first product, first sold in 1884 and eventually evolving into Buchanan’s ‘Black & White’ c1904.
