Laura,
I realize your post is from 03', but curious what you found. I think I have the same or similar bowl. It measures about 5 1/2 inches accross. It came from my Great Grandparents home, and my Grandmother was born in 1906, so it is quite old. I've always thought it may be of value, but after internet research it appears it is not. I think it is beautiful and enjoy looking at it in my cupboard. I don't see the 7's on my bowl, but a "36" or "96" in blue in above the makers mark. If you see this an have any info. I' d appreciate it.
