My first thought was 'no way am I going to click on a link in a members very first post'. But I checked it out on a safe computer and it is ok to click on. Terrible photos. I don't know what to make of the piercing in the stretcher band and tailpiece. Looks like somebody has gone to work on it with a drill.
I'm not certain, but it COULD BE the banjo which was briefly visible in the movie INDIANA JONES and the LAST CRUSADE". Visible for a very brief moment, in the scene with all the drinking cups, including the Holy Grail. Legend has it that it is the banjo played by Jesus at the Last Picnic, a week or two before the Last Supper.
