Good afternoon from Spain!

I am trying to restore a Rollei 35 camera with Tessar lens. I managed to repair the light meter and the stuck shutter, but after the second roll of test film the blade pinion broke due to material fatigue.

According to the service manual, it is the part number 67:

I have been unable to find this part for sale and I feel it's not worth buying a broken camera for such a small issue.

Does anyone know a seller who can have this part in stock?

Thank you in advance for your help.
