Re. LAGGING OF EXHAUST SYSTEM.

To confirm our conversation re. lagging for 25 HP.

With the recent standardisation of the exhaust system as fitted to 18.G.IV., the covering for the lagging should be made with sheet Nickel, instead of Staybrite. We have run a 10,000 mile test with this material on a down bake pipe, with no detrimental results.
