On the Photograph of Dr. Bakers rifle, there is what appears to be a large pin (approx 3/8" dia)in the side of the receiver below the receiver barrel ring and above the lever pin.

I have seen similar pins on more than one photograph of Zischang modified Borchardts. Does anyone know what the purpose of this pin is? It must serve some function, although it's not to be found on factory made Borchardts.
