Denix has put out a couple of versions of the P08, over the years.
Both have screw-heads visible on the left side - maybe to stop what used to happen with the early RMI-MGC P08's: the take down lever used to fall out and get lost!
One version has a screw in the take-down lever; the other version had two below the firing bars on the receiver.
Here's some photos for comparison.
TWO SCREWSONE SCREWNOTE ALSO: The trigger appears to differ on each model.
It looks like the auction is for the one at the top, as suggested by Metradio.'
