You could, in reality, easily repair and refit a barrel to it, and if a few measurements are taken first, make it identical to the original except for any original barrel stampings like company logos etc.
Or, you could get a gunsmith to drill out the old bore and fit a relined barrel liner and hide the refit completely. But that's quite specialised.
You would have to take into account certain profiles and find the spot to machine, or cut the barrel off. Generally somewhere in front of the receiver, halfway under the rear sight would be a great spot to hide it. The sight seems to be quite rearward and a reasonable spot to hide the join.
You would set it up in a lathe in a 4-jaw chuck with the barrel end at the jaws. The receiver sticking out of the headstock should be clocked centre of the bolt raceway (make a machined sliding-fit fake bolt to clock off would be easiest, because on old guns the bolt raceway is often oval. Then check outside of the chamber end is concentric to the bore, I bet it won't be.
The old bore centre should be on the same centre as the bolt raceway, seeing as they were made as one piece and you would first assume the whole thing was centre-drilled and everything machined out from that.
So clock the ex-bore centre.
Then all that needs to be done is, use a boring bar to open up the chamber end for the new thread, cut the internal thread pitch either based on whether you're using an already second hand threaded barrel, or machine your own on both and fit to remove all headspace.
You would want a barrel profile that is larger than the original to machine down as identical to the old one. Well, I would anyway.
The barrel will have a shoulder machined on to tighten on, and this shoulder should be the same diameter as the receiver to hide the join and keep the original profile. Once clocked, you can find the top dead centre and refit any open sights to complete the job.
To get a gunsmith to do this would be expensive, and you would have a long wait.
If you are determined to do it yourself, and know how to use the equipment, you could easily do it yourself.
I would find it a great project, quite easy actually and great fun.
All you will need is a suitable new barrel, and a chamber reamer. You can get one of them under $100 in ebay.
Many will say, why bother? Well, some will say that, then spend all their time in front of the TV or keyboard drinking diabetes. Instead, someone with the gear would have great enjoyment doing that instead, over a few evenings in the shed.
It can be done, and a great project.
But yes, you'd have to have the gear, but many handy blokes do.
