As per Fractured, Thomas has to roll separately to spot each item, be sure to specify in the roll itself which one is for what item.
The swords are sheathed at his waist, bandoliers across the small of his back, batons secreted away in pockets, and pistol in an ankle sheath (which means it's covered by his pant leg).
Also, keep in mind that even if Thomas can pierce the Obfuscations if something's not obviously visible (such as the batons or pistol) he still doesn't necessarily know it's there. I imagine there'd be further rolls for that.
