both have a circle [recess] with upward dimple in the center …the hammer has refinishing area where the auto hook was … so makes them ? thxs
Would you like to rephrase that in a manner that would allow someone to understand what exactly, you are asking and describing?
Markings on the hammer like this: (except in the shape that you discribed?)

These are from my DD LPK and I have also seen the same markings in FN and Colt weapons.

like the one with circle [recess] like that but with a dimple outward in the center …no other marks …sorry about any misunderstandings !
