Back in the 70s, a music shop in Bath St in Glasgow (McCormicks?) had a left-handed, electric, Martin tenor guitar in their window. It was apparently ordered, but never collected, by a member of a quasi-folk group of the time called The Settlers who were fairly well-known from TV.
Bearing in mind the relative scarcity of left-handed tenor guitar players wanting an electric and prepared to pay Martin prices, the price started at £750 and gradually dropped to £450!

I often wonder what eventually happened to it.
