I am new to this. I have inherited an Edison Phonograph from my parents. I needs help identifying it and getting parts. It does play. But I think the needle, as I call it, is wore and needs replaced. It's the point that actually sits in the grooves on the "record" as it turns. Any help would be greatly appreciated. The plate inside reads: Edison Disc Phonograph S19 SM74727 What is this info mean? Where can I get parts? Thanks in advance for any help.
OK: what you have is an S-19 "Sheraton" model. As the designation says, it was introduced in 1919, and was on the market at least up into 1927.
You will probably want to get the reproducer rebuilt, besides replacing the stylus. The best way to test whether the stylus needs to be replaced, is to run it on the blank area after the end of a recording: if it leaves scratches there, then it should be replaced. Wyatt Markus is the man to go to in this case: he goes by "MicaMonster" on the Talking Machine Forum (TMF). He will rebuild your reproducer, with a new diamond stylus, gaskets, and diaphragm, for a reasonable cost. I cannot recommend him highly enough.
Aside from the reproducer, it is always good to clean and re-lubricate the motor for best performance. I hope this advice is useful to you.
