Wow, this is hard to say, as the sword is sheathed, however based on the date of death it would likely be an Oakeshott type XII (contemporary with the type often depicted in the Maciejowski Bible). It could also be a type XVI, though that would make it a very early example. Google "Oakeshott Sword Typeology" for more information on the various types of swords. As for suppliers, if you haven't done so, check out Albion. They're pricey but their products are absolutely first-rate; ditto for Arms & Armor (A&A), who will also take commissions if you wanted something custom made. KoA (Kult of Athena) carries Del Tin, which are considered mid-level production swords. Be prepared to pay extra for a scabbard (which will need to be custom made for your sword, should you decide to purchase one). Hope this helps!
