Need a critique of a K Date

[Thor]

Interesting Safety markings, appears to have NO paint in there! Most Mauser Lugers will have transverse (not longitudinal) mill markings across the top of the front toggle link and breech block at the extractor. Many of the markings looked engraved touched up as they have sharp walls. A nice job of restoration in my book. The strawing seems too light but like JS said could be light reflection. My early strawing pictures looked that way too. The rear of the frame just above the lanyard loop should have up and down mill markings not across like DWMs. I dont see any pictures of that area to check this. Just my thoughts, I could be all wet!
Even restored, this pistol is worth quite a bit of money IMO, I have gotten some very substantial offers for my 1st Variation K date even though folks are told it is restored and the magazines were made to match the gun and are NOT original to it! Sear Bar appears to say 89 and not 19.
