Trying to find out info on my set of china from Edwin Knowles. I have found just a picture of a sugar bowl in my search. It is white with gold scalloped edges and green flowers around the edges and in the middle of the pieces.

This mark was one of two used between 1901 and 1948 !! You can find it here and how to date the set !!
