Well for me anyway, you have my email, send me a pic and I can give you a price, but I have to warn you it's like a $40 minimum with shipping and all and goes up also if you need a new sheath. I would hope I don't have to make a new guard.
Do you not have the means to remove the old handle, (hacksaw will do) and put a new one on? I presume it is a hidden tang as most Norwegian blades were and that makes putting a new handle on pretty easy. Files, sandpaper, epoxy, a drill gun and bits would do it. Lots of handle choices out there from Dymondwood to exotic bone or antler. All the knife supply places have blocks and scales.
Heck you can build the old handle up with some acraglas and sand it down to suit your hand. Texas Knife supply even sells do it yourself acrylic kits for making handles so you could build the handle up with that.
