Personal thoughts -->> 1962
Why
1st look at the left edge of the 6, straight not indent like an 8 has.
2nd upper right of the 6 has a horizonal line, with extra paint going to the top of the bottom circle.
According to two different sources, production ceased in 1976. So that makes it 1962 by default. It doesn’t make sense for it to have been made 4 years after its replacement was issued.

No but it still looks like 1982 to me, however, I accept that some may read it as 1962.
That's the thing you see, there is a leg for an "L" but only feint. (This may be harder to see on cheap laptops.)
The "8" is fairly obviously an "8" and I'm not going to pretend that it's a "6" when it isn't.
My immediate reaction when I saw the name in the shell was that it was German made, with "Messel" either the name of the maker or the place that it was made in Germany.
As you well know many European countries used the M1 style of helmet and a miss-matched shell/liner would explain a 1982 dated helmet shell on a French liner. (We can see that the liner is obviously French.)
