It was called router-crafter and sold through Sears for its entire run.
Highly elaborate spindles with corkscrew or vertical flutes or any number of other designs are possible.
Whoever said they were fast was lying. They are ponderously slow to set up and it takes many passes to complete a design. But its all possible.
There is kind of a resurgence in these and since they are no longer made, the price can be fairly high lately.
This is mostly due to another tool exactly the same, except 4 times the size, called Legacy if I'm not mistaken. You can do porch posts and other sizable work on it. The Legacy goes in the $10,000 range.
I have one and its instruction book I would let go of. Its missing one small part as I recall, and postage would be high (probably $30 or more) since its way too big to fit into any kind of reduced postage box.
