The Swiss RUAG company uses the code letters PS and FS code letters -followed by a 4-digit number- on some of its box labels to indicate the lot numbers.
As far as I’ve understood PS means something like Probe/Prototyp Serie, and FS means Fertigung Serie.
Can any of the German members please explain the difference between Prototyp and Fertigung?
It’s confusing to me because Prototyp means of course ‘experimental’, and Fertigung should mean ‘production’.
However, I’ve seen both SF and FS codes ONLY on boxes of experimental cartridges. Why does RUAG place FS codes on boxes that contain experimental cartridges?
