Worlds of Ultima: The Savage Empire/Weapons and armors

Each character can equip up to four items: a weapon, a shield, an armor and a necklace.

Also, characters have four equipment slots that are unused in the game: headgear, footwear, left ring and right ring. These are "leftovers" from the Ultima 6 game engine.

Weapons
Modern weapons can only be used by modern men (Avatar, Rafkin, Jimmy, Johann). Two-handed weapons cannot be used with a shield.

The attack value of the weapons is approximate, and based on the ranking of the manual. W. stands for "weight"; it is especially relevant when it may limit the amunt of ammunition that can be carried; 1 Eodonian stone is approximately 1 wordlwide kilogram (kg), or 0.16 US-only stones (s.).

Shields
Shields can be equipped only with a one-hand weapon.

Necklaces
Apparently, necklaces have no effect. Still, there is an equipment slot specific for them.
