The (very short) section on weapons in YS p 202, with a little bit more on YS 322, with a short mention on grenades on YS 325.
The game isn't supposed to be that equipment heavy.
But the weapon ratings would look something like this:
Weapon: 1
Some Pocket and hold out pistols, target pistols
Knives
Other "hand" weapons, such as brass knuckles, etc
Weapon: 2
Higher powered pocket and hold-out pistols, the vast majority of all combat handguns
Larger hand weapons (bats, batons, staff, very large knives, most 1 handed swords, chains, etc)
Weapon: 3
OMG! hand cannons (.44 magnum, .50 AE, etc)
Assault and hunting rifles
Shotguns
Light and medium machine guns
Extremely well made 1 handed swords, and similar
Large 2-handed melee weapons (pole arms, large axes, greatswords, etc)
Weapon: 4
Heavy machine guns (50 BMG, 14.5 mm, etc)
Anti-material rifles (50 BMG, 14.5mm, etc)
Hand grenades (+ Area: 1, or possibly only weapon: 3 for less energetic versions)
Very well made 2-handed melee weapons, or 1 handed weapons for things with hulking size
Weapon: 5
Larger explosive devices (ex: land mines, possibly + area: 2)
Ridiculous melee weapons (cars, swords the size of cars, trees, that kind of thing)
Vehicular manslaughter
Auto-cannons (such as those found on aircraft, attack helicopters, and infantry fighting vehicles)
Weapon: 8-10
Tank guns, anti-tank rockets, artillery pieces, etc
-----------
Then for armor, really there's only (potentially) concealable armor:1 and (always) obvious armor: 2
