Look-Alike Sets

2 other sets reuse the 3D models of Undermine Weaponry’s one-hand, shield, two-hand, held in off-hand and ranged, most shared models first:

Prized Aspirant's Arsenal (The War Within, 16 pieces): the same one-hand, shield, two-hand, held in off-hand and ranged models, recoloured.
Prized Warmonger's Arsenal (The War Within, 22 pieces): the same one-hand, shield, two-hand, held in off-hand and ranged models, in the same colours.

Matched in the game files: each piece’s ItemDisplayInfo names its 3D model and texture. The same model with another texture is a recolour. Only pieces with a 3D model of their own (helms, shoulders, cloaks, weapons, shields, off-hands and some belts and robes) can be compared this way; pieces drawn from textures alone are left out.
