De Vaucouleurs Atlas Description:

The inner pseudoring is a well-defined feature of this moderately inclined spiral. We interpret the galaxy as a ``late" Sab type because of its extensive resolution into knots and outer spiral arms. The RC3 type is clearly too early and must have been based on an inadequate image.
