Rolleiflex 3.5E Type 1

[Digital Mischief]

I'm in the process of testing a Rolleiflex 3.5E Type 1 my mom picked up a garage sale. I did notice it was missing the knob on the lower film spool. Does anyone know where I can get part for this particular camera?

If not, I would like to just test it and sell if possible.

Thanks
