Three porcelain spools. The two at the back in the photo seem to be the same shape, although they are embossed differently. The bottom photo shows the embossings: "Seyler / 255" and "Peirce / 355". They both appear to have been stamped so that the letters are raised against a recessed background.

The spool in front in the top photo is unembossed.

These are pieces I was lucky enough to have in my possession for just a few days before delivering them to their new owner. I liked them so much, I decided to photograph some of them and post them for reference.
