Well, much as I would like to follow in your collector/re-enactor footstpeps, keep in mind that I am-----ah--------Barta is a bit out of my price range.
We all do what we can.
I have an extensive firearms and Katana collection as well, and I have even traded collectible firearms to get a look at a sword that would, for good reason, not be acceptable to you.
Have you contacted Odin Historical Swords? http://odinblades.com
He mostly handmakes knives but he has a selection of Handmade swords.
Unfortunately, even his works are out of my league, at least for the time being.
I spoke to the one man owner and he mostly focuses on knives and he said his sword prices and time frames have not been updated.
I noted to him that Western reproduction swords appears to becoming VERY popular----but his market is in NYC for knives mostly.
If you haven't checked him out, maybe it might be worth a call.
It's a shame your favorite maker is getting so exspensive.
But, my first Hanwei Katana was only $200 and the Shinto Katan is now prices at $900, and they are not custom blades.
