In the paperback reprint of Freeman's book in 2016 I made some suggested Freeman classifications (such as Obverse 2* for the 145 tooth obverse that you found and 4* for Gouby's obverse G) but, unless a revised version of Freeman is agreed and published, they can only ever be suggestions with no formal authority. With Michael Freeman no longer interested in the subject, I guess we are left with Michael Gouby who, at least, is open to recording new varieties and types with their associated Gouby identifier.
