Isn't this Camera the Pocket Instamatic 20?

It is! Renamed it.
Thanks!

In 1972, Kodak introduced the Pocket Instamatic series for its new 110 format. The model 20 camera, model 30, and model 40 belong to the average range of Kodak pocket Instamatic. The most visible difference between the three models resides in the color of the shutter release button. They all have a sliding lens cover to protect the lens but it does not lock the shutter release, it does however put a diagonal red line through the viewfinder when closed to warn you. These cameras sold for less than $30. They have a mechanical shutter with a unique speed of 1/100 of a second without a flash Magicube attached and commutes automatically to 1/40 of a second when using a Magicube. It has a fixed focus three coated 25mm lens with a 9.5 f-stop. The set came with one roll of 110 film, one Magicube, a carry strap, the camera, instruction booklet, and instructions on how to get your free flash cube extender to help prevent red eye by raising the cube and still automatically turning to the next flash bulb. The dimensions are 4.9 inches long, 2.2 inches wide, and 1.1 inches high. The Pocket Instamatic 20 four year run ended in 1976. Other features are a frame count view window in the back cover, a ¼ inch 20 thread tripod socket, and a handy carry wrist strap.

Does it have a battery in it? What powers the flashcube?
