Feature photo above, taken December 2018:    Heintzman model D 6′ grand rebuilt by Ralph Thorn Pianos. Built in Toronto in 1920, this is a high-quality piano, even better now that it is rebuilt using the advances in knowledge of string scaling and hammer making.  A rebuilt piano can look like new, sound and play like new.  Below are two more photos of the same instrument.
