Hello everybody, I just got this lock at an antique shop. The owner told me he had this lock for so many years and it is broken. I played around a bit and had a response on all dials. After a couple of minutes it was open. The shop owner was really blown away and gave it as a present to me. Does anyone have some information about that lock. I also would like to find the patents.
Any info would be fine, thanks
Oliver
