British WWI Combat helmet questions

[Schelberg]

Im looking for a WWI British MKI combat helmet complete with liner and chinstrap but I have some doubts :
I know there are several types of markings HS (Hadfields Ltd. Sheffield),
FS (Thomas Firth & Sons Ltd. Sheffield), HV (W. Hutton & Sons Sheffield & Vickers Ltd. ) DF (James Dixons & Sons and Thomas Firth & Sons) and FKS ( ??? ) + a nr.
Are they all the steel suppliers initial? And the nr. ?
Were all used for combat purposes?
And could you please develope FKS initials?
Were they all rough paint?
Last question, were they all marked with a red stamp under the liner?

Here is a list of known maker's marks:

FKS has not been definitively identified, but some people think it may be another mark for Firth & Sons.

As far as I know, the number refers to the batch of steel.

I don't think there were any specifically civilian Brodies manufactured during WWI. I have seen a number of WWI helmets that were used by firefighters after the war though.

From the factory, rimmed Brodies had rough paint, though varying amounts of sand produced different degrees of roughness. The earlier rimless Brodies came from the factory with a smooth apple-green paint. Field repaints led to a wide variation in paint textures and colors.

Not all liners have the red Brodies stamp. I believe the stamps first appeared in 1917. Some Brodies that were issued to American troops had the liners replaced, so you will sometimes see American manufacturer stamps.
