variable capacitor
#1

When cleaning the variable capacitor I have seen that has a broken horseshoe pin. 

This is a problem for the operation ?.

You are probably ok. It's used the ground the rotor . Just make sure that the other one is good and clean. Use a bit of DE Oxit to clean it up.

Thank you very much.
I'll finish cleaning and I will use it well.

Cleaning may well do the job. It might be possible to fabricate a new piece if you want to go further. If cleaning restores proper function you may want to just let it be. One of the set screws looks like the head is broken off and considerable rust is present on the others. Set screws can be a real pain to deal with. Use caution with any chemicals to make sure not to get any on plastic materials nearby.

Apart from the horseshoe clips, these rotor plates need a bending tweak.

Hopefully, that's just an optical illusion in the photo. Continue looking to the left bank of plates. It looks like the circumference of the plates ends right there.

I think it is due to the photo angle. They look OK to me.

The sheets are fine, it is the effect of the photograph.
I have cleaned the forks and facing down the defect.

I know it would be a pain but I would grind off the rivets that hold the forks, clean all of the surfaces (especially the cap frame where the fork makes contact), and put it back together using screws.  There's an awful lot of oxidation on the frame and it could make for a very noisy and intermittent tuning.  A Dremel tool with a small grinding will quickly cut the rivets.  The whole operation should take less than ten minutes.

If the rivet is removed for cleaning, after it has become to be riveted.
