I keep reading about the laments (?) of Varangian reenactors that virtually nothing about their looks is known for certain. Most if not all of their kit (Byzantine/Russian-like lamellar over mail, splinted limbs etc) are either imagined, speculated or conjectured from their place of origin/from their Byzantine master.
For lamellar armor, as far as I am aware, Byzantine lamellar (or at least the reconstruction of it) looks nothing like the Parthia and/or Chinese style lamellar, but Russian style is much be closer to the Mongol/Chinese style.
The dead giveaway is the hand protection, which really wasn't all that common until 11-13th century.
