Heintzman piano what year was it made?

I have a Heintzman baby grand upright piano apartment size serial number 100574 I have tried to find what year it was made and what it maybe worth.
Thanks

Hi Nadine,

Thank you for showing interest in our site.

For a list of some major Canadian piano makers, with serial numbers coinciding with dates of manufacture. You will see a long list for the Heintzman company. Hopfully you'll find your's as well.
