This rare plate has a corner clipped off, and a few areas of touch-up which is easily seen in the photos.

This is where the touch-up is: The top of the "D" and upper left mounting slot area; a smaller area on the upper left vertical edge; a spot on the third digit; and finally, a small dab of black above the upper right mounting slot.

The areas that are original porcelain have nice gloss.

See the close-up photos for detail.
