At 4'10" and shot...why are you doing anything with it?  It looks like more work than it will ever be worth.....Could be a nightmare while awake!

Double overstrung? Both the bass and aux. bridge are cantilevered . The thing is shot so it's hard to make any judgements on what it may have sounded like,but it's interesting at any rate.  More pics to follow.
