Hi From New Brunswick .Just wondering where on your trillium is the info placed about Richmond Hill ? Is it a 1300 or a 4500 model? I see your front window is not a jalousie type either. I have a '76 1300 and I don't have the paper label on my closet door, it was removed long ago by a PO. I have no idea where it was built. Hope you enjoy your Trillium as much as I do mine ! Duane
