Silver marks are like a secret language. I found a book at the public library that gave a lot of them. And you might try eBay because they have tutorials for sellers. I have a Sheffield plate, but it's from the UK. One of the collectible ones, sliver-plated copper.

Have you tried an image search on Google, not just keyword? If you find something that looks useful, go to the page where it originated.

Still editing all day, the project looks good but isn't finished yet. We want to send it to the printer tomorrow, so we'll be doing some work on it in the morning. I didn't get into the yard, except to play with the dogs.
