Hi folks,
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.
This is a large undertaking and, admittedly, I am a bit daunted, but I shall do my best.
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?
For those with C-19's, please supplement the above information to include the following addendums to the list of criteria that I've asked for previously:
12) Is the reproducer, horn throat, and other hardware on the turntable gold plated or gun-metal?
13) Is the record storage door held open by a rod at the top, center shelf or the bottom of the cabinet?
14) Are the numbered strips for the record storage 1-36 on both strips or 1-36 on the top strip and 37-72 on the bottom strip?
15) Does the governor have 2 springs or 3 springs?
If you would rather remain anonymous, please feel free to PM me here, or you can email me at FPratt1426 (at) gmail (dot) com, instead of posting a reply.
Your participation and comments are truly appreciated, thank you,
Fran
