Pentax on cover of Popular Photography

Happened to be in the library today, and glanced at the May issue of Popular Photography. There was a picture of a camera covered in mud - so well covered that you couldn't identify it. However the lens designation was very clear: Pentax DA 18-55!

Unfortunately the lens was missing the key letters "WR". It's likely that the art department destroyed the lens in the setup for this picture, or in the subsequent cleanup.
