Possibly a Thomas Ibbotson Infill Smoother

The problem with a number of my infill planes is that the makers name is not marked on the body of the plane.

Amongst by collection of infill planes is a fine 15 1/2 in. Thomas Norris Panel Plane.

One of the planes I inherited was a nice little early infill plane. It is 6 5/8 in. long with a 1 3/4 in. wide blade. With the blade held in place by a wooden wedge.
