Nope this is the Moldvay basic set. IIRC weapons did either d4, d6, d8, or d10. Two handed swords and pole-arms did d10, daggers did d4, and lots of things did d6 (arrows for sure, not positive on hand axes though I think battle axes and longswords did 1d8).
Actually, the standard was still 1d6. Variable weapon damage was included, but as an option.
p. B25 said:AMOUNT OF DAMAGE: All weapon attacks by characters (PC or NPC) will do 1–6 (1d6) points of damage, adjusted by Strength and magical bonuses, if applicable. If the Variable Weapon Damage system (hereafter) is used, check the weapon type to find how much damage each weapon will do (adjusted by Strength and magical bonuses or penalties).
^_^ Hmm...the guideline lawyers could argue that magical penalties only apply when using the variable weapon damage option.
