I have the HAI 7-funnel version, and the Delphin final design, also a decent model.
The HAI / Youngerman 7 funnel version is wrong in that the triple turrets should be superfiring.
The hull was too narrow forward (and aft ) for a triple turret so the end turrets were the twins.
The model has this reversed, and it's nearly impossible to fix as the turrets are part of the casting, not separate.
The Ten Twenty 3D print is fabulous. Much better than the HAI or the Dephin.
