The use of the 4 Ringe Gewehr Lauf Stahl was an attempt to deceive the end user was getting tubes of the same Quality as the coveted 3 Ringe Gewehr Lauf Stahl by Krupp. 4 Ringe Special Gewehr Lauf Stahl - Gewehrlaufstahl was actually made @ Edelstahlwerk Freital and sourced from Edelstahlwerk Freital. So that is the word from the authority in Suhl.

>>ESW<< denotes Edelstahwerek.

>>BGH - Freital Edelstahl<< supplied steel to Ernst Thälmann Werke and other mechanics in Suhl.
