Thanks, Martin. That's what I feared might be the case. I would very much like to see what you've found re. Standards. I have one Standard in my collection that I can add to your list. I'll send the info on mine to you in a day or two.
Looking forward to seeing your spreadsheet. Thanks!
On at least some Edison serial numbers, I note that the number matches to a degree, how many of that model are being sold. Bill Cahill

Do you have any information on Edison Fireside Combination phonographs? Mine is a Model A with serial number 7493. I am a new member of the forum and will appreciate any guidance you can provide on possible date of manufacture.
