Are you sure that's the machine serial number? I'm not finding that number in my books. Is there a dash number on it? Like D21p-5 or -6? The -6s were from the '90s, and it's not one of those, the shape of the sides is wrong for that.
Just looking at it, it's either new or old, because it's not like the ones I'm familiar with. could it be only 6-7 years old?
