lot old industrial spools of thread, grubby white, black, neutral colors for rustic vintage display

Lot of vintage heavy duty sewing thread on big old spools and cones - most of this was used for sewing canvas, it's very strong and heavy weight. There's ten spools in this lot, shown all together in the first photo.

The spools are dusty and spotted from years of storage, but they're still great pieces for display (and quite a bit of usable thread if you're fine with some discoloration).
