where are you guys finding these old-style scandi axes
They aren't something that you are likely to find at a garage sale.
In my opinion, your best bet is eBay (domestic and international, many countries have their own ".xx" at the end).
Then there are private trades/sales, Tradera, or a foreign "Craigslist" with someone over there to potentially bid for you, pay for you if need be, receive, pick up, and then post it to you internationally.
In order to do that beyond just bidding you do have to put a certain amount of trust in another person whom you havent met in real life - sale, buy, or trade.
It's about axes and using them.
That part is pretty universal.
