Coronation was a bar line and bears an original Heisey Company name. The pattern was made from 1935 to 1957. It was used for some Heisey etchings and cuttings. The Ibex carving on this piece is of unknown origin. Heisey applied for a design patent for the soda in this pattern on 2/7/1940. Here is that patent: http://chataboutdg.com/gallery/details.php?image_id=13648
