Joe,
I have a 30's Gibson archback guitar that was my father's that had a hardcase and fitted canvas cover with leather seam trim. The canvas was fine but the stitching and leather crumbled apart and left me with just pieces of canvas. I don't think I'm going to spend the money to have it rebuilt. Something you might consider is inspecting the strength of the seams and if they are weak, have it stitched over before it falls apart. Old stitching was likely cotton or linen. Over stitching with new polyester thread will hold the seam together indefinitely.
