Clearly you know nothing about salting hides. For mounts the hides are salted prior to tanning. That is 100% of them at every tannery, every time. Furs for sale by trappers are flint dried, which means no salt, just air-dried. Once they go in to the tanning process they are resoaked and salted before the process starts. Lots of hides fail at that point.
If you are tanning the hide yourself or sending it in for tanning it should be salted ASAP. Period, every time. On mounts it is easy enough to fix small slips and such by cutting them out and sewing them closed, except on the face for obvious reasons. The hide rolled into the inside is the last part to dry, or to freeze when put in the freezer. Faces rolled in are the most likely to slip. It is also the area with the most likely places to rot, regardless the way you are drying.
Feel free to screw it up any way you like or want to like. It should be obvious the above is true but feel free to try to figure out where there might be the tiniest flaw...
