Hi folks, this project is moving along at a brisk pace!
As I mentioned when I began my research, I need your help in compiling a spreadsheet that will culminate in an historically accurate reference for the phonograph community to use for the assessment and restoration of these wonderful New Edison Diamond Disc Phonographs.
"The instrument that holds the musical ear." - Advertisement,
The Talking Machine World, April 15, 1915 issue, ppg. 12 & 13.
It is my intention to compile as much data as I can find to establish, exactly or as closely as I can, when significant production changes were made to the C250 and C19 Diamond Disc Phonographs over their lifetimes. Once compiled, I feel that I should be able to demonstrate a chronological history of these changes and, hopefully, identify precisely when these changes were implemented by Thomas A. Edison Inc., from a serialization standpoint and when.
The following are particular features and characteristics that I am looking for:
1.
Model Designation: (C-250 or C-19)
2.
Serial Number:
3.
Bedplate Pinstriping: Y/N
4.
"Official Laboratory" Medallion: Round/Pentagonal/None
5.
Exact Wording of the Medallion: Please be precise (Abbreviated signature, for example)
6.
Record Storage: Drawers or Shelves?
7.
Cabinet Wood Type: Mahogany or Oak?
8.
Duncan Stop?: Y/N
9.
Dealer Tag: Name/Address, Location On Machine
10.
Original Dated Sales Receipt/Shipping Documentation, etc.: (Dates are particularly noteworthy):
11.
Grille cloth? Color?
