And chances are, the reproducer part that you are looking through is Mica and not glass, although there were reproducers that did use glass diaphragms, I think they were only found in cylinder machines.

I am going through my moms stuff and came across what looks to me to be the arm (that holds the needle on a phonograph). On the round part, it has glass and behind it there is a washer shaped circle(looks like red cardboard) with the name of NIRONA and Germany underneath it. Can you give me any info on this? Thx everyone. >From the Desk of Kat Hall Review Coordinator for Champagne Books Head Reader for Champagne Books www.champagnebooks.com _______________________________________________ Phono-L mailing list http://phono-l.oldcrank.org
