These are a couple of infill shoulder planes used to trim tenon shoulders for fine work. The word 'infill' refers to the wood that is encased in the cast iron body and sole. The blade is held by a wedge which inserts from the top rear. You can see it protrude with a rounded end in the photos. The dark plane has a rosewood infill and is made by Slater, probably in the early part of this century. The lighter one has an infill that looks like fruitwood, though I suppose it could be boxwood. It has no name and one of the tightest mouths I have ever seen on a plane.
