Fernando Rocha Jose I have never heard of Gustav Lehmann, but the serial number might indicate it is a Samick product. However, from what you describe, it sounds like a problem a lot of 10 - 12 year old Young Chang pianos are having. The action brackets are made of a pot metal that actually gets bigger over time. The only solution is to replace them. If this is indeed a Young Chang product, you need to contact either Young Chang, or the company that represents Lehmann. I don't know who that is.
