HK G3 identification

[MG42UK]

Hi Guys

I recently got a deact HK G3, but am struggling to identify whether it is a Bundeswehr issue, private market model, or issued to another armed force/service.

A pic of the stamped numbers on the left side of the mag housing are below. The trigger group is non-matching with the numbers '603' but with a big 'X' seeming to cross them out over the number.

Any guidance/info would be appreciated

Upon closer examination, there are two small eagle marks on the left of the receiver (pic below), I would assume this is a Bundeswehr acceptance mark?

Anyone who is more informed on this, would be great to get this validated.

Thanks

Mystery solved! I found an identical stamping on another forum that confirms what I have are two Bundeswehr acceptance stamps, so this is 100% a German army rife (see below)
