And how are the cork gaskets? The ones I've seen (and replaced) seem rather
brittle and most of the time have deformed and come out from under the flat
ring.

That's what I like about this group, you learn something new about your
passion all the time. The earliest reproducer I have is on my C-250, the one
with the screwed on stylus plate. This machine is from 1916. It does have
cork gaskets so they must have been been replaced very early on. I've had
several reproducers with the screw-on plates and they all have had cork.
They must have kept the dealers busy retrofitting!
Thanks for the info.
