This is the outside of my 1905 Knabe-Angelus. She is a plain simple piano with a clear window in the center to see the hammers. No fancy carvings here, almost an arts and crafts simplicity.
The original keys were replaced before we bought the piano.
It was well cared for with only slight piles of mouse hoarding under the hammers. This piano has not been in a flood nor outside as many do end up. There was soot from a wood stove on the inside of the casements. Someone took great care of the piano. If we did want to do a full restoration it would run about $10-$20K. But she is in tune and plays very well so for now we are happy.
