For me proof about Welz glass is contained in this German book containing thousands of marks and signatures from glass factories all over Europe, It is Called the Glasmarken Lexikon.The second image has the marks for Welz. The third and fourth images contain Pieces with the marks from the book.
You may question the attribution and believe that many pieces with these marks are not Welz but Kralik or Ruckl or just Czechoslovakian export glass...but here is the evidence. You can believe it until more documents come to light, deny it and believe these are only marks of origin put on by distributors.
