Rick, all of the bedrocks had lateral adjusting levers. Stanley added the lateral lever feature to (most of) their bench planes in 1884. The first versions of the bedrocks were produced in 1898 and all had the familiar circular disc lateral adjustment lever. How is yours broken? Is the disc gone or is the entire lever missing? The top of the frog should have a round hole at the top center for mounting the lateral. BTW, the frog is not broken at the top is it? For some reason I've seen a lot more broken bedrock frogs that regular frogs, especially ones with breakage at the top. If the lateral is just botched, it can be replaced, but as Jim said it's not light hearted work and requires some procedure and patience. Those concerns are founded, and great care must be taken to not beat on the cast iron frog or it will break. PM me if you would like and I'll hook you up with a new lateral lever and instructions on how to replace it (without breaking the frog). :icon_thum:icon_thum
