Looking for info on my new Gerhard Heintzman

[twylafaere]

Hello everyone! I am brand new to this website and I am delighted to be here! I just recently became the new loving owner of an old Gerhard Heintzman cabinet grand and I can't seem to find much information on it other than some basics and I am wondering if anyone knows anything about this particular make?  The serial number is: 18117. It's absolutely stunning and I love it so much, it would just be nice to know what year it was made and whatnot Thank you so much for your time!
