What should I offer for S/42 1939 luger (UPDATED)

[MilitaryTorch]

I ended up buying 1939 S/42 Luger so I am going to upload few pictures.
I now need to find grips and actually find out what they should be marked as? Eagle 63?
What do you think the grips need to be marked as?

Also I have to say that I am not too bright when it comes to figuring out what a sear safety is.

If you have grips for sale that I am looking for please let me know.

Thank you,
Steve

PS Bore is shiny and all numbers match inside. I also need to figure out which tool is correct for the gun. Droop Eagle 63? or maybe S/42 marked one?
