Coverley - Production Engineer} E/JNR.{Charles L. Jenner}1/HP.3.10.34. re 25-HP. We send you herewith:- LeC.4106 showing the exhaust manifold with air cooling fins. This should be tried experimentally. The addition of the fins makes the weight of the manifold 3 lbs heavier. E/JNR.{Charles L. Jenner} | ||
