the BB shell is a Silva (Italian brand) product, those IC lugs look similar to some that Long Shen (Taiwan brand) sold as "Nash" models, but I have a memory that LS was copied them from a short-lived Italian brand. Can't recall what brand that may have been, perhaps Silva as well.
Correct that it's not a Ciocc, but as to who built it: could be anybody...looks decently made, tho.
