Looks like Chinese crap.

I've read with English Longcase clocks that cast brass bushing rods should be used, machined to size and then riveted in and filed flush and then the oil sink recut.

The idea of using the cast brass's colour matches the old brass used on the English clocks which is not the same as modern brass.

Do carriage clocks also require special treatment like this?

Or is it just a matter that the clock in question standard 'off the shelf' Bergeon bushes were used and then the oil sink not recut on the back of them to match the original hole?

I never filed the bush flat in the plate, too much danger of damaging the plate. I would turn the bush to the correct depth using my lathe. You never rivet the bush in, you lightly hammer it home. The rest of what you have said is pretty well right.

I never liked bergeon bushes, again I would make my own using the lathe and using brass rod stock, measuring pivot size width and depth of the hole and plate, after the bush had been cut countersink the hole to fit the old oil sink and lightly hammer in, if you have got everything right you just turn the countersink a few times and it matches and becomes invisible.

Yes I have just set myself up to be able bush clock plates. Bushed a couple of pivot holes on an old wall clock in my night classes I had and then full of confidence proceeded onto my next two practice clocks and unbelievably neither of the clocks required any bushes which annoyed me greatly as that was what I was hoping to practice on them.

I need to wait now until I have time to work on my junk Ansonia movement which I know needs atleast 2 pivot holes bushed

With American clocks your Ansonia is American the movement will have lantern pinions, with this type you do not need the same type of fit for the pivot as you do with a movement that has the normal type of pinon, you can afford for it to be quite loose, but if the holes are oval and look wore then re-bushing is required, check the pivots too as the steel in American clocks can be quite soft.
