The Queen Mary at Garvel docks in 2016. Since this photo was taken much work has been done to the vessel and she is now berthed at the Science Centre in Glasgow but not yet open to the public. The Queen Mary I remember in the 1970's had just one large yellow funnel in the centre so was easily distinguished from the other two large Clyde steamers with 2 funnels, The Dutchess of Hamilton and PS Waverly,
