LUMIX GH1 by Panasonic - Mirrorless Interchangeable Lens Camera

This is a consignment from my father.
I have no knowledge of cameras or lenses, so I may not be able to answer specialized questions, but I will answer anything if you let me know (e.g., adding images), so please feel free to ask.
I have many cameras and lenses at the moment and plan to list them, but there are also many accessories, so there is a possibility that some of them are mixed up or incorrect. Please check the images for any scratches, etc.
Price negotiations are possible, but not by a large amount.

Condition:
Working has been confirmed.
Although no lens is included, I have confirmed that it is possible to take pictures by attaching a lens I have.

There is some light dirt and paint peeling due to aging. I don't think there are any scratches or dents. In my amateur opinion, it is a beautiful item with few scratches.
There is something like white dust inside the Akamaru in the 11th image.
The included accessories are only the battery and charger.
Thank you.
