Do people even use carving knives anymore?
You could go nuts (nice but pricey)

I think if it has history then take the old knife to a maker and see if they can sharpen it a make it useful. Blenheim forge in SE London might be worth a call. Although a bit of googling might come up with something more local to you.
My 2p.
A carving knife doesn't do a great deal more than a chef's knife 99% of the time, so I'd go for aesthetics as much as anything. So that's really down to your taste.
I'm guessing the blade it too worn away? Do you think you could remove the handle and replace it?
