Scale model of a massive double bearing steel casting. Your guess is as good as ours to what its original function was. Forging press? Part of a rolling or planing mill? Massive lathe head stock? Muffler bearings for a battleship?
Other items in photos shown for size comparison - Not included.
Scale model is for display and operating model railroad load / modelling and is not a child's toy.
For use by railroad modelers age 14 years minimum.
