By all means make a decoration out of it, but only if you do something render that rifle from ever being fired, weld the chamber, fill the bore, weld the bolt closed, something, anything. Not sure if you have kids or not but someday the story and memory of that rifle could be lost.
Pretty good idea - never know what's going to happen with it in the distant future and that receiver/those parts could be either very soft or very hard, or both depending on whether they cooled slowly or quickly - one blast from a hose in there and metal could've hardened to the point of stress cracking, or could be soft as heck if it cooled slowly in the ashes. Maybe a rod hammered into the chamber and a cut into the bottom of the receiver ring - stops the barrel from chambering and the receiver from functioning but is invisible without disassembly.
If you wanted to dump a ton of money into the gun it might be salvageable. I'm really not an expert but to my mind you'd need to:
- Get it thoroughly cleaned and de-scaled, and you'd lose metal doing that, so bore and most surfaces would end up out of spec. Scale forms whenever metal is heated and oxidized. it's the flaky black, hard crumbly stuff that comes off like scales from the metal. Probably also a lot of rust pitting by now too.
- Next get it tested. No idea what would be appropriate but non-destructive testing of some kind. Probably also have to check for warping while you're at it.
- If anything's excessively worn/reduced/damaged/cracked and reparable it would need to be cut away, straightened, welded/filled and then refinished. Depending on whether the metal was hard or soft it might need to be annealed to be worked or to reduce stress. I'm guessing after a fire the gun would at least to be annealed to make sure the metal was of the right hardness to work with.
- Finally everything would have to be properly heat treated and rehardened to whatever hardness it was supposed to be.
That's how I'd approach it if I were to try to take it on at least... but hey, you're getting advice from the internet so it's probably not totally correct
