Re. 19 The blade must be bent back at the tip, 30° being probably a very suitable angle, but it must be bent forward further along as shown to prevent fouling the back plate. Fig 2. We have a spare plate with rocker and a double break, which may serve for the above modification. Signed H.{Arthur M. Hanbury - Head Complaints} Allen This Sheet must be filed on completion of the work. | ||
