We have a 1918 William Knabe 5'2" baby grand piano for sale. Our son has played it for 7 years and it is in very good condition. He has perfect pitch and has kept it in tune. It is a Boston model and we have the serial number that shows what year it was built.
This is a baby grand piano that my 80 year old mom had for 20 years. She enjoyed it very much. She moved into a new and smaller apartment from a home. She had it tuned yearly and it sounds great. We have it stored now easy to access.
