Sears Router Crafter was made by Trend Machinery in Britain. It's still being made and is called the Routerlathe, but you have to order it directly from Trend at

You can also download Trend's manual for the Routerlathe. It's much more detailed than the original Sears manual. You can also buy the special fluting bits from Trend.
