Jim, This stuff is not rocket science, and with your background in silver collectibles I know that you already know this. But there are I'm certain some, who might not fully grasp all of the significance of what you've posted.
The stamps you posted can be used on a teapot, candelabra, or any other item made from silver. That's what silver makers did. They reused the stamps on what they made until they wore out.
The cast in place fake "GAHR/Crown/Circle-Double Crescent(?)" marks cannot be used for anything else. They can only be used to make more fake "Gahr" wide connectors. This was a one time effort to make a batch of fake parts - with the pattern to be discarded when they ran out of daggers to modify. FP
