A picture would be helpful. Although they share common ancestors and technology, metal-cased office dictation equipment is not technically considered to be a 'phonograph' because they were produced long after the time when the use of phonographs split into two branches: office dictation and home entertainment. The office machines became standardized using 6" long cylinders with a 150 threads-per-inch pitch, while the home entertainment format standardized at 100 (later 200) tpi, and a 4" length. Home entertainment and dictation machines had different standardized rotational speeds as well. The two formats aren't compatible. Edison abandoned the term 'Phonograph' for dictation equipment with the formation of the Ediphone division. Columbia Graphophone Co. did the same in applying the term 'Graphophone' to office equipment and formed Dictaphone. Office dictation equipment has limited interest among phonograph collectors because of the incompatible format and office-oriented use.

the "classroom phonograph" was also metal with a metal cygnet horn and an adapter for recording it was made from metal to better withstand the riggers of a classroom
its my understanding that the business model e was a natural evolution into a dictation machine

Is this the same machine as yours?
I lifted this picture from the following site.(Which you've probably already seen)
There are some period photos & advertising related artwork on this site, but nothing related to schematics unfortunately. It appears that even the early metal cased models were referred to as Edison Business Phonographs &/or dictation machines until 1917 when Edison started using the trade name "Ediphone".
