A while back I bought a lot of tools at an estate and I'm left with a whole bunch of router cutters and I can't find which router it goes with. Those small 1/4" cutters don't fit Stanley 71 or 71-1/2, Veritas or Stanley 271. Any idea?

The left cutter is for a Stanley 271, the centre one is the mysterious one and the one the right is a regular cutter for Stanley 71.
