I recently acquired my father-in-law’s old 604 smoother. I immediately read up on everything Bedrock, and upon taking it apart, the one thing that shouts BEDROCK to me, (aside from the 600 number), is the single full size machined surface that the frog sits on. If you compare to other Stanley or other brands, the frog sits on as many as four small machined pads. The Bedrock series was intended to have the largest mating surface between the frog and the shoe as possible.

Like mvflaim said, if it’s not a 600 series, it’s not a bedrock. You probably have a plane that has cannibalized parts.
