• Rosewood knob is shaped like a hot air balloon, and has a distinct bead turned into its base.
• The brass depth adjustment nut is solid (sometimes of a two-piece construction), with "BAILEY, WOODS & CO." "BOSTON" "PATENTED" "AUG. 31, 1858, AUG. 6, 1867" stamped into it. Only the lower portion of the name "WOODS" is visible. The nut has a right-hand thread.
• "L. BAILEY'S" "PATENT" "DEC. 24, 1867" is stamped on the top of the iron and cap iron.
• The back of the lever cap is solid and has a banjo-shaped spring.
• The frog has a rounded back (the top of it where it faces the (tote)). It is held into place by screws with round heads.
• The bottom casting's receiver for the frog is shaped like the letter "I".
• The size of the plane (stock #, e.g. #4, #6, etc.) is incised into the underside of the frog and the lever cap. This isn't listed in the book I reference, but every example of these early planes I've examined has it.
