What material are the Aperture blades in a Compound Shutter made from? The broken one appears to be fiber based.
Thanks in advance.

I seem to recall that they were a paper-based product, maybe lacquered paper?

Rather paper hardened with Phenol Formaldehyde resin I guess, without knowing these blades in particular.
