Yes, and it's sad when i saw someone asking the originality of their new USA made M1+liner but later they'll realize their helmet is a euro clone.
And to be honest, it's extremely difficult for me to obtain the USA wartime made swivel bail, rear seam in here. The euro clone shell is plenty in here and both shell is really similar!
... but i can trace the front seam, fixed bail easily in here. I see 2 shells still sale in the antique market in my hometown.
But this doesn't mean i'm against the euro clone. The diversity of the euro clone made those helmet really interesting to studied. I hope someone will make that thread soon.
