Cleanliness

The slide rule is moderately soiled, with particulates and grime in the creases along the sides where the cursor moves. There is also grime build-up on the underside of the cursor.

Surface

The back of the slide rule covered in light scratches throughout. The text on the back of the slide rule is heavily worn and discoloured to green or absent. Unclear what the original colour of the text was, possible gold. The text on the front of the leather cover is worn, with sections removed.

Materials

The clear window on the right end of the back side of the slide rule is yellowed. The leather cover is considerably creased from handling and use, with the leather softened around the corners. The surface of the leather is also worn off in places, particularly on the back.

Structure

The top right and left corners of the upper section of the front of the slide rule are broken, with sections missing.
