Finnish used M16/18

I'm reviewing my late Father-in-law's collection of Finnish army helmets. I've only just now found the Finnish forum after posting a couple of helmets under the German helmet section.

I believe this one is a Finnish used M18 helmet? Maker stamp is ET.

It has some interesting markings on the inside rim, including the owners name. There is part of a symbol which looks a bit like one I've seen on another Finnish anti-aircraft unit helmet - like a spider.

Is the white leather liner typical of those fitted by the Finns?

German m/17 and refurbished in Finland before ww2.

Finnish pre-war green and likely re-placed new liner cushion pads. Unless you find german stamps in cushion leather.

Original german m/17 factory paint green is darker.

Here's a couple more photos which show the serial number on the inside dome "S42N" and liner band with split pin.
