John, I guess I don't understand your question. Not sure of the "push rod cocking" definition.
Daryl,
Sorry for the confusion.
It is only my observation of my personal guns. My RE has cocking hook in the barrel lug and uses push rods to trip the ejectors. But my "Batavia Ejector" models with do not use a cocking hook on the lug to cock the hammers. All my ejector guns have cocking(push) rods running through the frame from forend to the hammers. The forend has rollers that engage the rods. Both my Baker Standard ( boxlock nonejector) use cocking rods. I believe that the Baker Ejector (boxlock) also uses the push rod cocking. Again, just my observations.
John
