With respect to these pieces, I was notified by another site that this is an "unidentified pattern by Thomas." Hopefully someone might be able to help us out with these.
While you are waiting for your response, I thought I would mention a website called
www.replacements.co m . They offer replacement pieces for old and new dinnerware- china, stone, crystal glass, silver, collectibles etc. They have a FREE email service if you send them a photo of what you're looking for they will identify the pattern for you.
It's a great service with a gigantic inventory. It has been great for me in searching for old silverware patterns.
