Original Soennecken 1000 D.R.P. ang. Bakelite writing pad with battery operated light and mechanical pencil. The pencil is stored on the side (it is somewhat hard to take out). When you remove the pencil, the light turns on. I don't have a battery on hand to test it. It requires a special European battery that should be available at a camera shop. It is in good condition; there is some corrosion in the battery compartment. It measures about 6" by 3 1/4"
