Does this piano look mouldy and rusty?

[robertsrommelhoekje]

I am able to buy this Petrof piano. It sounds lovely, although some keys need to be tuned. I'm a beginner and have no experience in anything related to the inner workings of a piano. It seems to look alright, but I'm not sure if the bass strings are rusty, or that some of the felt has mould or not. I do think there's a little bit of an old wood piano smell coming from the inside.

Is there anything that stands out?

Thank you for reading!
