Double Helical Cut Tooth Mill Pinions - These were widely used in steel mills.  Double Helical gears feature increased tooth mesh contact area vs straight cut gears, for the ultimate in power transmission, yet without the side thrust common to single helical gears, resulting in a lighter (cheaper) bearing.   We have this O Scale product in a somewhat smaller size but got a customer request for a bigger one that better fits the venerable Lionel F9 well car.  

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.
