Conn Hellebergs have varied a lot over the years in flatness of the rim. I'm sure you can find many examples from different years of flatter and rounder rims that are all marked "Conn Helleberg". The smaller 7B version is usually a little rounder.
I make one of my available rim shapes flat like the flatter versions of the Helleberg. It has a lot of advantages for those who like it totally flat. Everybody else hates it.
