I have at least 3 piggy back presses

Some of the Parts I see in your picture could be used on a piggy back.. Some could be used on the turrent press (internet pic) https://www.optics-world.nl/winkel/product_info.php?products_id=840
i think many parts are interchangable to some degree

My rcbs primer tubes I also use on my Hornady progressive

Texas Gun,

The top three parts comprise the primer feed system for the Piggyback and the spring loaded punch is probably one of the primer punches. I can't be sure, but the spring may be the return spring that attaches to the primer slide bar. The flat aluminum bar with the two holes and hair pin replaces the handle on the RCBS powder measure and the long steel rod and wedge shaped part with the key slot activate the powder measure when a case is present on the shell holder at the powder charge station. The chunk of black plastic on the left, the five prong star, and the large L-shaped piece are not for the Piggy Back. The single aluminum tube appears to be an older RCBS primer tube that was replaced by the updated tubes in the plastic bag or it may be a component of the L-shaped part. The primer tubes encased in plastic are standard RCBS primer tubes and can be used in the Piggyback as well as other RCBS machines.

The original powder drop system shown in your picture was replaced on later versions of the Piggyback with the case activated powder drop system which is a much better system and is still the standard RCBS powder dispensing system.

One of the worst things that happens when using SNIPIT is quality of image loss. I hope these help (pictures from the Manual):

I'm pretty sure the spring is the "Return Spring" for the PBII Transfer Bar.

The "Primer Ram and Spring" - IDK. They are not for a Rock Chucker or Universal Priming Tool.

The other components as Gus has outlined.
