That is a tough one. If it a piece of history I would hang it on the wall and call it a day. If you're up for a challenge give it a go. About half way through you will be wishing you paid the guy to do it. But hey if that guy can do it so can you. And I say that not trying to be sarcastic.
You will have to look at YouTube videos about removing a neck if it a dovetail joint. And about removing soundboards. Just be careful with the top because it will be a template for your new top. Once you have the new top braced (If it has a radius to the top you may need a radius dish to build the proper dome into the top) and voiced you need to attach it. You will need a lot of cam clamps or a go bar deck to do it right. After it is attached you will have to use a router to cut new binding channels. There are a lot of ways to go about it. You may even want to just buy a gramil and cut them by hand. It is a little more work but it is harder to mess up. Once you have your new bindings installed into your fresh cut channel scrape them flush and get ready to apply the finish usually 6 coats, 3 per day sanding in between. Buff and now were ready to attach the neck. Hopefully the geometry is all good. You may need to make a new bridge if something is off. Bridge placement is where you break out the heavy guns. You mess this up and the thing will never play in tune.
Hope my short and very lacking description of what you will be up against does not sway you against attempting the project. It will be a challenge.
