Gold coloured. Model unknown. Took the handles off to paint/update them, now the knobs just will not operate the mechanism at all. Knobs will not turn or operate thestriking mechanism. No, it has nothing to do with the painting process. It just needs some adjustment about which I know nothing. HELP!!

In its currently disassembled state, there is nothing locking the mechanism. You are correct that the C shaped half-circle shaft is what pulls the latch back when turned.
If you cannot push the latch back with your finger, the anti-jimmy device has had a piece break in it.
I had this happen on a bathroom door latch about two weeks ago, probably made by the same manufacturer as the shape of the lock actuator rod and latch actuator are exactly the same.
If you look at it, the lock actuator rod (the center piece you were turning) has a taper section just where it passes through the latch pull which means that during assembly, you manually push the latch back and it passes straight through.
In order to get clearance so the lock actuator rod will pass through, I pried the folded piece that they pass through till I got clearance so the shafts would pull out. I then squeezed the folded piece back together and pushed the latch out. It didn't even require taking the door off the hinges.
Replace the whole door knob/latch assembly with new and you're back in action.
You're going to have to drill a larger hole for the new handles, which should completely encompass the old hole.
Head on down to your local hardware store (or cruse the internet), and look for a door handle installation jig like this Irwin® Door Lock Installation Kit
Example only, these jigs are available from many different manufacturers
It comes with the proper size hole saws to set up a door for modern locksets, and makes alignment of the holes quick and easy. Simply attach the jig where you want it, and drill the holes with the supplied hole saws.

Making a wild assumption since we don't have enough information: I'm guessing that what you have is a grade-3 Schlage cylindrical privacy set of the sort that's available from every hardware store in the country. There are three pieces to this unit -- an outer knob with a hole in it, an inner knob with the thumbturn, and the latch mechanism.
The installation guides on the Schlage website are for one-side-keyed knobs, but the principle is the same -- in fact, the mechanism is close to being the same.
If you look at step 6 in that guide (sorry, I don't have that one image by itself), you will notice that on the inner knob with the turnpiece, they tell you to look into the knob and make sure the slot is horizontal. If you look closely, you'll also see that the flat piece which runs from knob to knob is horizontal.
That's what you got wrong. It is possible to assemble the lock with these pieces rotated 90 degrees -- but only if you rotate them in opposite directions, with the result that they're both at their limit and each keeps the other from operating. This also has the side effect of tying up the knobs in the locked position.
(This is a general hazard when assembling mechanisms that are only designed to operate through part of their rotation rather than being able to spin endlessly. The position of the parts in this cycle is known as their "timing". You got the timing wrong.)
Remove the knobs, and reinstall them with the flat bar horizontal and the thumbpiece turned to match it. That should cure the problem, unless you've managed to do something more weird than usual.
