This early pointer was called the first laser pointer although it is not a laser. This is a little light projector that works with a bulb and the top end of it can be turned to focus the arrow. This thing, from when I tried it, can really project rather far. It projects a white arrow when you push the white button. Comes in the original box with paperwork and two new old stock bulbs still wrapped in protective paper. This piece is in mint condition and never used. Must have been stored for many years and has natural age from just sitting around for 63 years.
