I think we made a pistol grip 3/4 body instrument, but it was before I was taking pictures of everything. I'll see if I can find a template.
The one you've got on the right is similare to the Balance K - just the cutaway is offset in the Balance K so the upper horn doesn't look too long for the rest of the body shape. It's pretty difficult to change only one part or curve on a bass when you make a change, the whole shape needs to be evaluated so it doesn't look like something was just stuck in place. But that's why we make 'em custom.
