So I measured everything today...
BB shell is 67mm wide, looks to be faced on non drive side, threads are actually swiss, when i tried those iso cups i screwed them in just about 5mm, after threading them in 3/4 of the way they started binding.
Tube diameters (without paint):
Seat tube 28mm
Top tube 26mm
Down tube 26mm
Headtube 32mm
