This is a classic vintage "Alien Head" Craftsman model 103.23700 6-inch thickness planer, manufactured by King-Seeley. This unit is exceptionally clean and is in original unrestored condition.
The thickness planer is mounted on a custom made welded steel stand. It is much stronger than the original Craftsman 12 gauge sheet metal stands. The motor is a Dayton 1/2 HP 1725 RPM industrial grade motor rather than the consumer-grade Craftsman motors.
The cast iron body is completely solid, no cracks or welds. The table raises and lowers smoothly. There is no play in any of the shafts, blades are sharp, runs smoothly. It has never been disassembled or refurbished, everything is in original condition and works perfectly. My father was the original owner, it has been kept in a dehumidified dry basement.
I have the original manual for it and a set of 6 spare unused blades.
