Absolutely! that knife can be restored to an acceptable condition. If you want to keep it original you need to find other knives like this with good parts. Maybe you can find a knife with a good front handle and then another with a good back handle. You might also look for a bail and punch and also have the blades cleaned up a bit. When you have found all of the parts you need it wouldn't be hard to reassemble the knife with better parts. A good way to find parts is to put an ad on AAPK and then also watch ebay for knives like yours that are damaged. The alternative is to buy modern handle material from a company like Culpepper and have the knife modified. Only my 2¢ but I would keep it original as possible and look for parts. It might surprise you but I don't think those parts would be that hard to find.
You can never bet too much money on the winning horse.
