[Phono-L] Edison C reproducer cork gasket?

[Ron L'Herault]

I've just taken apart a Model C reproducer and it has cork gaskets and a
non-ferrous but not copper colored diaphragm (nickel plated).  I doubt it is
aluminum the center button is soldered.   The limit pin is rather crudely
soldered (excess solder present) but the rest of the reproducer looks well
made.  Is it a repro?  It had a rather rattley sound and I am hoping that
the modern rubber gaskets will improve the sound.
