OK, no local source for those stickers. Ully and Michael, do we team up for the stickers and buttons ? Please PM me....
I also updated my Berzerk restoratoin thread on BYOAC forum:

Inside the 3 Berzerks I recently found, there were also 3 envelopes and each contained a full set of documentation.
Apart from the schematics, instruction cards in various languages (English, German, French, Dutch) and a monitor schematic, there was also of course the manual.
However, I soon found out that the manual was nothing more than a bunch of photo copies of what looks like the concept for the actual manual.
The first thing (and maybe the biggest thing) to notice is that the "cover" is hand-drawn in a rough sketch style. Also, the text with the drawings are hand-written and the pages with texts look like they came from a typewriter.
Here's the cover of the concept manual:

Here's the cover of the "final" manual:

Also, the trouble-shooting section (explaining about the beeps) is only a very short list of possible causes, compared to the elaborate explanations on the version of the manual that I have found at several sources on the internet.
Although there is not much more (actually, less) info in this manual, I thought it would be interesting from an archival and collecting point of view.
The machines I found had relatively early serial nrs. (in the 2000 and 3000) so it looks like Stern put in some pre-production manuals with the early games. Maybe also because these were shipped to Europe ? (Transport time).
Anyway, I scanned it and here is the PDF:
