Vintage Marble Pen Stand by Parker

A vintage -my guess is the 1970s or earlier- marble pen stand for a pen made by Parker in the US or Canada. It also has a functioning perpetual calendar for the day, month and day of the week. The marble is mostly white colored with some brown; the actual holder and calendar are brass. The rear of the calendar has a ding. The stand is 7" wide by 2 1/2" deep" by 2 3/4" high.
