I found—and ordered—the same two-handed sword on eBay that was sold out from another seller, i.e., this one:
It’s fairly simple in design… and hopefully not too crude in it’s craftsmanship… But the game at the start is taking place during an iron shortage.
It does look to me like a weapon that would be found on the Sword Coast of Faerun circa 1368 DR. Minsc’s hands will cover the blue plastic wrapping on the handle. According to seller’s shipping chart it should arrive in 1-2 weeks.
Update: It turns out the seller cautioned that this could take up the three months to arrive because of the pandemic, so they offered a refund, which I took them up on. So Minsc won’t be getting this sword. But in the next post I’ll provide update about a better choice of sword for him that I just ordered .
