While dis-assembling a Zeiss Ikon Ikoflex 1a TLR i ran across some small discs which are used in the focusing mechanism (inside the Slide Block).

Just wondering if somebody knows from which material these discs are made ?

In an Ikoflex 1b service manual they are called Pressure Disc and Friction Disc.
The discs are about 2 mm's in diameter and can be seen here : Discs

I disassembled a 1a before and I do not recall seeing any disc. May be that is why my focusing knob has free play in it. It still focuses fine but just annoying. If you find out what the materials are, can you please post them here. Thanks...

Hoped that some "old school" serviceman had a clou as i don't like the idea of performing a destructive investigation ;-)

Today dis-assembled an Ikoflex 1a of a later production date then the first one.
It suffered from lousy focusing. In this one the Pressure Disc is clearly made from metal.
The Friction Discs also seem to be made of another material then in my first Ikoflex. Could be that they are made from some kind of carbon.

I posted an image here : Second focusing system
