I've added more photos of the interior and the diaphragm of the reproducer. Note the aluminum diaphragm! Also, when I took it apart, the old gaskets were hard and flaked away, apparently this is not a modern reworking of this reproducer, but was done many years ago. The paper gaskets were in place too. Note the grooves cut in the back of the weight to accept the tails of the springs. This is a rather advanced job. John Robles http://s197.photobucket.com/user/john9ten/library/Odd%20reproducer

I have seen weights made of aluminum with springs like that. In 1915 and after the copper CHK diaphragms were nickel plated and Edison continued to make them into the 1920's. Are the ground away areas nickel plated? > Date: Mon, 16 Sep 2013 10:22:06 -0700 > From: john9...@pacbell.net > To: phono-l@oldcrank.org > Subject: [Phono-L] Odd cylinder reproducer > > Hello all > How about some opinions on this reproducer?
