Nikon HR Plan Apo 1.6x objective lens for SMZ microscopes

Nikon HR Plan Apo 1.6x objective lens for SMZ microscopes. Lens is in good condition. Glass is perfect, housing has some signs of wear but nothing serious. Was used on an SMZ800 but I've been told it also fits an SMZ1000 or SMZ1500, but I don't have access to these scopes to confirm this.
