I have two cameras I don't need a Konica C35 and a Yashica Electo 35GSN. Both are not working for whatever reason. Actually they both "work" the C35 has a meter issue and only fires at 1/500th and bulb and the Yashica looks like it was taken apart, but it works 50% of the time.

Was wondering if it's worth keeping them for parts/screws or should I just sell them or even just throw them away?
