The 003 was the thickness of a piece of note paper......you put a piece of paper in the contacts ,rotated the motor,and when the paper could just be pulled out ,that was considered to be good enough for the "break" point of the contacts where spark occurrred............as mentioned the correct full opening was .012" to .015".....................................as someone once said at a vintage bike run......"Do get yourself a set of feeler gauges ,they only cost sixpence"......."Sixpence....sixpence?...when I were't lad,there wer'nt sixpence in't whole of Yorkshire"
