The worth it part depends on your reasons for having it restored. If your intent is to make money, or even see your money back, then to me the answer is no. But if, like me, you want the gun restored because you want to bring a quality gun back to life and enjoy it, without regard to what you might get for it down the line, then I say yes. You can't buy them on every street corner.
But, first thing to do is to get the barrels evaluated by someone with experience. That consists of bore and barrel wall thickness measurements, cracks, dents, loose ribs and an approximation of how bad/deep the pitting is. If you don't have a set of barrels then you are off to a bad start as far as spending money on a restoration. Although you can get tubes.
