Undated Simson Luger?

[JohnF]

Thank you very much Herb. There is no proof at all on the sideplate apart from the 2 digit S/N and no proofs on the grip screws or extractor. All small parts do have the correct 2 digit S/N though.
The eagle 6 does appear in a number of places as follows:
The take down lever
Twice on the right frame
The top of the barrel
The underside of the safety - this is not a clear stamp though
The right side of the front link of the toggle action - my technical vicabulary is not good!!
The top of the middle part of the toggle action.
The top of the rear part of the toggle action.
The right side of the trigger.
The front of the trigger guard.
The rear of the magazine release button - as visible on the right side of the pistol.
The bottom of the shoulder stock attachment.
The sliding bar that moves up when the safety is on.
The small angle cut part to the rear of the sideplate - there is a gap between this part and the bar mentioned above but it's cut at the same angle - apologies again for lack of proper terms.
That's all the eagle 6 markings that I can find. The only other thing that I would say is that the S marking looks to be in it's original place and there is no sign of this part having been altered.
Once again, many thanks for your help.
All the best,
John
