The large 2-piece in back says "Fletcher" on the top rim and "Patent" on the bottom rim. It is held together by wire, as is the small piece below it to the right. That one is embossed only with the letter "G". It resembles a spool, but again is a two-piece, held together by wire. The embossing on both is raised.

Next to it, at around 6-o-clock is a porcelain radio strain. To its left is a nail knob, and far left is a very small, smooth round spool. It is unembossed.

These are all part of a collection of porcelain insulators 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.
