I believe carbon fiber tonearms and headshells started appearing in the 1970s, so I doubt that your older Ortofon shells would be made of carbon fiber. Do your headshells look something like this?
As I recall, some of these vintage headshells have a cap that you can pop off, allowing the GE push-and-turn post to protrude through the top of the shell.

Subject: [ARSCLIST] Carbon Fiber head shells
Hello everyone. I just heard that carbon fiber headshells are the best.
Is that true?
I have a few old (late 50s-early 60s) Ortofon headshells and I'm wondering
if those are carbon fiber. Are there other excellent head shells for
screw-in tone arms?
Also, I need a push and turn GE cartridge installed into one of those Ortofon shells. Who can do it?
