Just thinking. I'd start with the right dia. and thread pitch in brass. That should be easy to find in a machine screw. Then I'd need a hacksaw blade, a file, pliers (or vice grip), a drill to make it easier, and about 1 minute for each one. Now I could also consider cheating a little by using a long machine screw to lock one knob onto the shaft and cutting it off flush, then with the remaining, make a set screw or just cut it so it doesn't stick out too far for the other knob.

I just did a quick search on McMaster Carr using 1/4" as the length. Found a few options. You can change the search options for more results. I'm not sure that these are what you are looking for but maybe.

That’s a lot more work than I was hoping for.

you might try here.
Is the problem the thread size or length? One of the places sells brass set screws that are 10-24.

So do the doors that go with that have a mortise lock?
I don't know if that site has it but you can buy replacement spindles that have holes through the then length wouldn't be an issue.

First, you don’t need that sharp a point. Second, I wouldn’t mess with brass screws, point the holes to the bottom and use standard steel set screws. Third, buy a 1/4 - 20 tap and run it into the existing holes so a common screw will fit. Done.
