You can order steel needles for your wind-up gramaphone from Kurt Nauck in Texas: http://65.36.235.139/Merchant2/merchant.mvc?Screen=PROD&Store_Code=NRC&Product_Code=112.105&Category_Code=112

Kurt sells them for about $15 for 500 new needles. He also runs amazing collectors' aucions of 78s and cylinders.

Or from Victrola Repair Service in Vermont:
http://www.together.net/~victrola/needles.html

They sell them by the hundred, for $4/100 plus shipping.

In theory, you were supposed to use a new needle every time you played a record, but almost nobody ever did that, which is why the grooves on so many old 78s are badly beat up. At three of four cents a time, what the heck--you might as well get a packet of new needles.
