Hi 2111
How do you identify that as an M14 Hammer? Just curious.
I have a NM M1 Trigger group that came off a 1962 or 1963 NM M1 that has a HR hammer. It is the TG that I asked about in another post.
The big difference that I see is how it is annotated.
On the NM TG it is marked :
HRA 5546008
The spare M1 hammers that I have are marked:
5546008 HR A or G
In the first case the HRA is before the part number and in the second case the HR follows the part number with either an "A" or "G"
FWIW
