We send you herewith drawing LeC.2091 shewing a modification embodying a strip of soft felt in the locality where the main underguard fits around the crankcase. The intention is to have 3 different thicknesses of felt available, and use these on either the sides or at the bottom as required to fill the space. The felt is secured to the underguard by aluminium wire staples. E.{Mr Elliott - Chief Engineer} | ||
