I have an L.E.N. Pratte Baby Grand Piano. The Serial # is 3951 or is this the model #? Does anyone know how old this piano would be? I don't know where to look on the internet to obtain information regarding the age of the piano or whether this is a quality piano. It is in perfect shape with a lovely sound. I noticed somewhere on one of these forums where someone referred to a Pratte piano as a lovely old dinosaur. I have obtained some history about the brand Pratte but I was looking to find out anything else I can about this type of piano. Thank you.
