Your telegram received :- " One and four exhaust valves Silchrome, anticipate " " these will fail with lead, should like report on " " condition of other valves. " We shall have to dismantle the Cylinder head again to give you the condition of the exhaust valves. We examined number three, which was in a good condition. With the use of the lead, you do not anticipate heads breaking off. There has been no indication of the valves stretching. The head of Number four broke off close to the head. The seating in the Cylindxr head did not need re-cutting. We will let you have the condition of the other valves after dismantling. ------------ G.W.Hancock G.{Mr Griffiths - Chief Accountant / Mr Gnapp} W. H.{Arthur M. Hanbury - Head Complaints} | ||
