Round Bone Stanhope Mechanical Pencil

This is a cute, little, smooth, white, bone pencil. The working mechanism appears to be nickel-plated brass. We just noticed an inch-long crack in the bone that may not show in our picture. The 6-view Stanhope is titled "A Memory of Ilfracombe/McKee Fecit". The pictures show the coast and countryside e.g. "The Castle Rock Lynton, Junction of Streams... etc." It measures 3 1/4".
