I'm sorry for your loss but WRT the rifle and bolt situation, if you like the rifle enough that you'd want to keep it for sentimental reasons or use it to hunt varmints yourself, then sending it off to the mfr certainly is one option as long as you're willing to absorb the costs involved. If keeping and shooting it, the memories evoked while out shooting, be it at the range or in the field, could both be well worth the cost, IMHO.
I'm kinda in the same boat with a rifle my late Dad (RIP, Dad) horse-traded with me about 35 or so years ago.
The original stock started cracking at the wrist on top plus a little in the left side. Why, I haven't a clue, but instead of buying just any hunk of wood to drop the barreled action in, I want to find an exact replica of the original stock as it came from Winchester. Great figure with black rosewood forearm cap, etc.
It was my primary hunting rifle for many years, having taken elk, mule deer and so on. With my hand loads it was quite the accurate deliverer, too, so I'd like to put it back in service, even if I can no longer hunt over Hill and Dale and it is relegated to shooting from the bench. (Sigh)
My point being, IF the rifle holds some intrinsic value to YOU and as long as the cost of buying a replacement bolt isn't stupid crazy expensive, it might be well worth it. To YOU.
Besides, it would make a nice heirloom to pass along to your kid(s) one day should you choose to do so.
Regardless, good luck in your quest.
