Hi, http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=007&item=170015155602 http://tinyurl.com/kctrb I have a gold Victrola No 4 reproducer that has what appears to be a ring that allows a No 2 mica to be held in a No 4 reproducer. Does anyone have any information on these? I will be happy to send a photo of mine, it appears to have been done a very long time ago. Steve
