Dutch M34 Helmet Restoration part 1

I own this helmet since my youth. It's one of my first helmets.
This helmet was used on a farm as a scoop to feed the pigs.
I got this helmet together with an US M1, also used as scoop.
As a little boy I cleaned it and painted it green.
The same color as my father used to paint the windows and doors of our house.

You can imagine how it looked like before cleaning after being used as a scoop for more than 30 years.
Unfortunately, I do not have any pictures of that green paint.

The following pictures were taken after removing the green paint, actually all paint.
To my surprise I found the signature of a removed helmet plate under the paint.
