I found one mention of Kinclaith in the 2013 version of The Whisky Bible by Jim Murray.
Kinclaith operated from 1957 to 1975 as a Lowland producer. Its listed as 'closed/dimolished' by Mr. Murray.
From Wikipedia : 'The Kinclaith was the last Malt whisky still built in Glasgow, within the Strathclyde Grain distillery complex, in 1958. The Kinclaith distillery was closed in 1975.'
Given the short life span the whisky's are rather rare and are more a collectors item!
