I google and found this page which has several links.

Here is a link that might be useful: grindley

Thanks for the link but I still don't find the pattern that this is and the stamp is different as well. Does any one know what 3-3 means??

Silly - how about showing the top side of the bowl-plate-whatever it may be? This isn't a game called "Three Guesses", and we're not clairvoyants!

I have the same exact set same stamp

I suspect that, like "cream petal" and "Ivory", that "satin white" is Grindley's way of referring to the background colour rather than the pattern. You could look through all the Grindley patterns on Replacements to find your pattern.
