Hello Bill,
Since your PMs ane not working I will post the following. I was talking with Gunter today on another matter and mentioned your needs. He thinks he may have what you need. All Knick parts have to be fitted, remember.
I was a wiz9to my standards) today with my 5E Knick at the Fort Bragg Clay Target center. 23/25 for each of 2 rounds of wobble trap. Good for me and me 1942 Knick!
Best with yours, Walt
