This old brass and steel dovetailed mitre plane with a beech bed and bone front infill and wedge, it is probably the oldest known 4" long example ever found. The smaller the English mitre plane of this sort of period the rarer they become. I have seen two and I used to own both of them, but they were marginally bigger, I can't remember exactly but somewhere about 5". One was by Buck and one was by Towel.
This plane has engraved on it's side Edw'd J. Davies and underneath MAKER.
What appear appear to be flutes on the top on the rear beech infill are the worn away soft parts of the annual rings. This plane is very old, we will never know exactly, it could be 150 or more years old.. If anyone knows differently please let me know.
