The Talking Machine Forum — For All Antique Phonographs & Recordings

Hello! I just picked up this Nirona phonograph. It has a broken or unhooked spring, and the reproducer is missing. Do anyone have advice on how to take this thing apart? Does the platter have to be tapped off with a hammer? It seems a bit corroded.

The reproducers for these seem to be rather hard to find... several I saw online had severe pot metal issues. I'm thinking of Frankenphoning it for now with a generic reproducer.
