These sell via the name "Pickguard Plus Pick Guards Acoustic 4pc Set Guitar Scratch Plate"
They might be OK for other guitars, but not appropriate for Harmony Sovereigns.
Shape is way off. And the edges are not beveled nicely like the original.
Below is an image of the Chinese pick guard on top of an original Harmony pick guard from an H1260. They got the curve OK, but the rest is off.
