I work as an intern at a museum and we're currently researching a sword in the collection that was claimed to have been found in the ground in Williston, Vermont in the early nineteenth century. Only the blade and guard remain and they're heavily corroded at this point, but the blade retains at least some of the original markings. The guard features curled quillons, which can be seen on the edge of the Tesh3 image attached below. I apologize that better pictures of the entire sword aren't available.
The blade reads Peter Tesh, but that search turned up few results. There's a ca. 1600 Peter Tesche Sword at the Metropolitan Museum of Art, but they don't have an image online for it. The book German Swords and Swordmakers mentions an Alsace Peter Tesch working in the years 1636-1657 as well as a Johan Peter Tesch working in the late eighteenth century with one date at 1795. I've also read that the maker Pedro de Velmonte was very well respected and that a Peter Tesche later used some of his markings which resemble the dotted markings around Peter's name on the blade. There was another sword posted in an article online with the name "Pedro Tesch" but the markings don't resemble anything on our blade.

I'm just curious if anybody here might have any information on these marks or the blade? We're trying to determine likely dates for the blade or whether it's a later forgery using a well-known name.

Thanks, any information would be much appreciated,
