Deletion of Blyth Education

Comment: I didn't find the depth of coverage necessary to pass  when doing the usual searches, but I see this company has been around since 1977, so there could well be sources that are not available online. I am erring on the side of deletion at the moment, but I could be persuaded if new sources come to light
