These lampshades have been restored with new fabric liners. The lampshades trims are the original trims. Antique lampshades, or most any lamp, have lampshades specific to the lamp. Often the cover fabric is in good condition but the liners are brittle. These shades can be restored with a liner repair.
Often people buy an antique lamp and when they get it home, the liner is brittle. Just something as simple as picking up the shade, and your fingers go right through the liner fabric. Any liner will get brittle and shred from light exposure and time. The new light bulbs will add many years to the restored shades.
It is always best to pick up any lampshade by the top spider wire.
The following are liner repairs, but with different fabrics.
