Plumbing – How to remove this single hole American Standard bathroom faucet

I'm assuming this is in reference to an outdoor garden faucet. If you can't get the old packing out, replace the entire faucet. But first, make sure you don't have a dope of a builder that would solder the threads. Try to unscrew the fixture from the wall (shutoff the outside water first). If it unscrews, then all you need to do is pickup some pipe dope and a new faucet from the store. Clean the old threads, put some pipe dope on the threads, and screw on the new fixture.

Does that whole round bulb part unscrew? It kinda looks like it might. Might spray some lime away on the whole works to get a better idea how it's put together. It looks like maybe the white part should unscrew. Like the white was the aerator but the screens have been pushed out.
