heavy bronze main entry set has the "Irish Leaf" pattern. It was used on all major door work, including the two sets of massive 300lb pocket doors that separated the ladies parlor on the west end of the building and the men's parlor on the east. This bronze piece is the heaviest set of hardware I know of, weighing in at just under 13 lbs.
Breezie is right on, as usual. Here is a pic of a similar lock used at the Broadwater Hotel in Helena MT (1889 - 1941):
