Hello, Sethallen1973, welcome to the forum!
A couple of years ago, I began an extensive project to compile a database chronicling the Edison Chippendale C 250 and C 19. I recently completed my series of 4 articles that was featured in
The Antique Phonograph -- the journal of
The Antique Phonograph Society. The series ran in 4 quarterly issues, from December 2015 through September 2016, detailing many variations of features that occurred between its introduction in 1915 up until its discontinuation.
If you would like to know more about the period of time in which your C 19 may have been produced, please visit the APS website introductory page, where my production estimates spreadsheet (in PDF form) is supplied for the general public to view, download, and use to help identify a few of the more prominent features found on the Chippendale throughout its lifetime.
This is a link to the APS website, if you're not familiar with the Society:

Click on the "Articles" tab, choose "Introductory", find
Edison C250/C19 Database; Production Estimates 1915-1925 by Francis W. Pratt, click on the "Read More" tab, and scroll down past the Albert Spaulding image to find the spreadsheet, and key PDF links.
In the meantime, would you please consider taking the survey that I began, in May 2014? It can be found here:

Scroll through the entire post beginning on page 1, if you'd like to read through the many (258+!) replies. There is a wealth of information contained within!
Best,
