Hi H&A members. Looking for a Styer-Hahn 9mm part

I am new to this site. I have a Styer-Hahn 1915 9x23 that and I purchased a 9x19 from IGB Austria what a beautiful shooter. My problem is the wedge, I did not have one and a gunsmith made one however it will slide all the way through the slide in either direction or will slide out with rapid shooting. I have another gunsmith working on a different wedge with stops however I really would like to locate an original manufactured wedge. Little help from my shooter friends?
