Shutter curtains on a Leica Ic

[frederikdalum]

Hi

I have recently inherited an old Leica Ic, with a 5cm Elmar lens on it. It is the model that did not have neither a viewfinder or rangefinder, but instead have one mounted on top.
My question is, I cant really tell if these shutter curtains are too old and need to be replaced?

I think it is attached as a photo to this post.

Thank you
Frederik
