On the case PeterThanks Micky. The bike was bought at Alexanders of Lothian Road here and owned by the same Embra family for decades. (My boyish snotty nose knew the window at Alexander's all too well from pressing against it, admiring the bikes!) I thought the story of the bike and its refurbishment would make a great wee feature for our local IAM rag. We might even be able to track down the family who owned it originally.
Cheers!
