My mate Greg brought his Mandolin into work today.Its got the biggest sound box I have ever seen on a Mandolin, The front to the base is separated by the sidebody of some 9 & a quarter inches. Its 8 and a quarter inches at it widest top and bottom and 16 and a half inches long, top and bottom ,without the neck. we sneaked into the photo Lab at work and I photo scanned the whole instument. got a complete colour print of the whole body which I plan to reproduce and make a replica.
