We are glad you find our malleable iron feed pipe effective in curing the chirp with the simple form of induction pipe jacket. We prefer not to use any more features in the jacket than are necessary. Regarding the silencer N. sch. 3004, this was made less bulky and simpler than the experimental one, and with the minimum of welding on it so as to be easy to produce. It is bound to require some development work, but we ought to persevere with it even if the experimental type is used for the time being. E.{Mr Elliott - Chief Engineer} | ||
