Stanley #71 1/2 Router Plane

Note the replacement knobs and the irregular adjuster. This adjuster applies downward adjustments only. To raise the blade you would loosen the clamp and manually slide it against the knob. (a replacement adjuster knob could be found on any 71 or 71 1/2 plane if desired)

Only 1 cutter come with it but other blades can be bought from Lee Valley.
