Hi,

The report states that there is no sediment As far as carbon the only reference is for:
CO: 14 microlitres/litre
CO2: 1219 microlitre/litre.
It then states that oxides of carbon gases are consistent with normal ageing.

The breather was discoloured and replaced but I dont know why. The summary said that all requirements are met apart from the heavy fibre content it fails the electric strength test. Smaller at the bottom it states that it is satisfactory for continued service but requires an oil change.

I took my time, I hurried up, The choice was mine, I didn't think enough
