Hi everyone, this is not for sale but i am looking for advise. I recived this as a present, i know the person that previously owned it and that it was bought for $1600 around 10 years. It was very rusted so my partner gave jt a light sand and olied it but we are unsure if that was the right thing to do. It doesn't sound as it should and we wonder if it can be tuned and if there is anyone that can help us
