When I started this tread, I already told you all that I made a list of German safe and vault manufacturers. I put in a lot of time and effort to make that list.
Thanks to the help of another forum member, I was able to add a few more names.
While I was still searching, another member told me that a list could be found on a particular site. I have indeed found it and of course a number of names that I had were also on it.I typed 70% of this list manually before I found out that there was an easier way to copy parts from the list.
When I placed the list here, the informant came up with the comment that I had just copied everything and did not take copyrights into account.It was never my intention to just ignore rules. If anyone feels insulted, I hereby apologize! The source was: Bruckner & Raum Tresortechinik Germany.

Then the next issue ... is a list of manufacturers a secret?
This is important history and I am sure it will not be misused in this forum group either.
In fact, it is exactly in the right place here!
