SMS Nassau built from a Ralph Coles Hull. Purchased along with Espana from Bob Pottle in 2001 or so. Four units with three guns and one pump, one spare gun assembly installed for parts and symmetry . Turrets are foamed and held in place with large Neodium magnets. Barrels are bent before they exit the turret to save space and enhance fit, I expected to replace them offten but these are the originals without any protection (Chrome Molly tight bore from McMaster Carr) and are three years old.
