This is a #3 Leonard Bailey smooth plane. All metal except for front knob, which may gave been replaced long ago. Original patent was 1867, and an improvement patent is stamped 1876 on the iron. These were made by Bailey from 1876 to 1888.
Front knob has a crack.
Otherwise all parts are present and only minor rust. I have not attempted to do more than wipe down and apply a bit of preservative to the metal parts.
