1. Helmet cost 4 BTC.
2. Sorry for my English. Not "reconstruction" but "historical reenactment" https://en.wikipedia.org/wiki/Historical_reenactment
Helmet has no original parts. I take a sample from this book https://ospreypublishing.com/the-vikings-hb?___store=osprey_ca&___from_store=osprey_usa
3. Helmet is now in Minsk, Belarus. I will pay delivery. Shipping to any country.
4. I do not quite understand about "escrow".  I'm new here.

I have a few more interesting things:

Used materials: steel, bronze, velvet.
