I'm not shooing you away or anything, just suggesting that you might have better luck posting this plate in the "What Is It?" forum. They have a much broader knowledge of objects outside of glass and pottery, and they're usually very quick at getting answers. Good luck!
Well they're usually pretty busy, and I'm sure you could do it yourself in less than a minute. I'd just copy and paste your text (and your pics are already uploaded so you won't need to do that again, they'll be in your attachments), and create a new thread in the "What Is It?" forum. Go for it! You'll get an ID much quicker.
