Thanks Glenn ,
As far as I know ,
There was no coating over an EM helmet ,they made the tombak shine like gold , you can imagine the elbow grease that went in after a march in the rain.
The officer helmets have an extra gold finish, to polish that would be a shame coz the finish will come off.
I have recently brought an Officer’s SGR. The nutsack of the lion has 7 stamped on it and the rear paw has 3 109. The lion is quite tarnished but a quick rub over to remove has lightly shined some areas. The shell is also very tarnished and needs a good clean with soapy water. Tarnish on the chin straps has started to affect the metal, so I figure a light clean is ok.
They are an amazing helmet and I consider myself quite lucky to have found one.
