None of the 7 NPCs with names beginning with "Sentry _____" associated with the Temple of Marr in North Freeport display the weapons they should be holding.
As follows are links to the P99 wiki page that has a pic of each sentry with weapon in hand:

The other NPCs inside the Temple of Marr have weapons (the ones who are supposed to).
Thanks.
