Differences between Schlage Primus and ASSA Twin Combi

[greyman]

I've had a look over previous posts related to this, but I still can't figure out whether there are any significant differences between Schlage Primus and ASSA Twin Combi 5800, except for the undercut groove on the key for the Combi. From pictures I've seen, the finger pins seem to be the same and both seem to be able to use both rotation and lift of the side pins. Any comments?

The schlage everest primus uses an undercut sidebar also.

primus combines rotatin and lift, I don't know for sure about assa, but I think its only lift.

The twin combi also uses rotation with lift if I recall correctly raimundo. I dont have any info in front of me as I am at work but I am certain the operation is identical. If there is any difference, it may be that the twin combi uses only 4 instead of 5 sidebar finger pins but I cannot remember for sure. I may be thinking of a zeiss ikon model there.

I got a theory that Assa Twin Combi is the same lock (except for the key profile perhaps) as the Schlage Everest Primus. I think they both use twist and lift pins, but I'm not sure if they both have 2 heights and 3 twists. They're the same from a design point of view - 6 pins and 5 side pins. Can someone confirm?
