Date of shako?

[Whatacoin]

Bought this shako today and can't find too much information on it. Everything leads to the US-Mexican war but there are materials such as the visor and strap which are not plastic but something else. Seems to be the band but I can't come up with much else. There is nothing inside the headstrap or inside.

I would not believe websites such as ebay where they are trying to sell something. I think you have a marching band Shako.
