Peter Wernig was one of the largest Ferlach gunmakers before WWI. He started at age 18 as a barrel forger. By 1867 he sold his first batch of complete guns. By late 1800s he had some 50 men working for him. In 1907 he sold his business to a group of Slovenian investors who organized a limited company but he remained a stock holder. He died just after WWI. This is only a short extraction from the chapter on him in my new book manuscript.
If you carefuly dechipher the numbers (with all the points) on the gun the year of production or rather proofing should show up. Is the gun marked WP by any chance?
With kind regards,
Jani
