This item is a very nice ENGLISH MAHOGANY PERPETUAL CALENDAR. As time goes on, we find these harder and harder to find particularly in this condition which is excellent. The basic problem with these tends to be the paper scrolls which over time become torn and replaced with mis-matches or become stained or ragged looking, not so in this case. The three scrolls - day, date and month - are in excellent condition and are original. The calendar measures 8 1/2"H, 5 1/2" W and 3" deep. The scrolls are mounted on brass turnings seen on the side of the calendar. They operate freely and smoothly. This one is in as good condition as one can find.
