They are in very good condition without any cracks in the bakelite. I cleaned a couple of them on the underneath part and scrubbed the back which started to take away some chrome and show through to the copper. But I did not clean any others.
You can see one of them on the second photo where I cleaned the underpart and how the chopper shows and you can compare to the one next to it that was not cleaned. I used a soft green scrubber. So I will leave cleaning the rest up to you if you have a gentler way to clean them without taking chrome away. Screws holes are 3 apart.
