German heer child helmet

[Helmcollector]

Came upon this child helmet for sale. Not that I intend to buy this one as I have not children and would be a little bit expensive to give this for his birthday (650 euro)
But I wander how on earth you could ever check his authenticity...should there be a stamp of a manufacturer ?
Finally found how to download pictures from a site that would not let do it...thanks to this forum (print screen, paste in paint)

They don’t fake these yet Erwin. Looks good to me. Expensive indeed but I don’t collect these so maybe price is correct.

This one will be even harder to find I guess...
