antique vintage silk sewing thread, cotton thread on large wood spools

Lot of assorted cotton sewing thread and silk sewing thread on good old wooden spools. The silk thread is on the two stand shaped spools (2 1/4" tall spools shown in the front of the first photo). All the rest of the thread in this lot is cotton.

There's a little fading or age discoloration and spotting to the outside wraps of some of these threads, but all seems strong and supple yet.
