Hi Andy, Your reproducer is an Edisonic or New Standard reproducer that started out as a regular DD reproducer and was converted to an Edisonic by the Edison Factory, since yours is such a late number it may have been converted and never sold as a regular reproducer. I have sent you a photo of the Dance off list, your reproducer does not have the spring on top of the diaphragm. Let me know if you got the off list e-mail you sent.
The C-19 originally came with a regular or standard DD reproducer, so the original owner most likely upgraded it to the Edisonic, however since the C-19 was available until August 1927 and the Edisonic came out in April 1927 if your C-19 is a late one you may have the original reproducer. What does your grill cloth look like and what is the serial number? LG is long play EM is one with Duncan stop LD is the Dance no letters & A to F Regular DD reproducer NS before the serial number Edisonic NS after the serial number Converted Edisonic Steve >This is interesting.
