APG Brass Knuckles
 

Do the APG version of the Brass Knuckles still exist in the Pathfinder 1E database? I have been trying to find scripting to allow Monk damage to be applied to a weapon but so far no luck.

Yes, wBrKnuckle is there. In the editor, go to Equipment, Weapon.
There's no scripting on them, they are tagged as Monk weapons though.

What do you mean by "Monk damage"? What exactly are you trying to do?

When the APG first came out, Brass Knuckles allowed Monks to apply the Monk Damage override to them as if they were unarmed attacks.

This was later errata'd to not allow this, but I would like to recreate the original APG version of the Knuckles.

I have a pre-errata copy, so I can see the text you refer to. Errata is always implemented in HL and the pre-errata version does not exist in HL.
You need to get the info on your current Unarmed Damage and then override the actual damage of the weapon you have. This should be possible, but beyond my current knowledge.
There is an adjustment that will change the damage: "Weapon Damage Override", but obviously you would have to activate it on a Hero each time.

Yeah, I was hoping to create a custom editor build that would do it for a player automatically, but I guess the adjustment will work. Thanks.
