A hardness test was one of my first thoughts too. However, the proximity to the last two digits of the serial number in these cases, plus the fact that so few parts have what appear to be hardness test dots in exterior places, makes me doubt it. I think hardness testing is more likely to have been done in a place not visable when the gun is assembled. The three dots on Thor's Erfurt are interesting but are deeper and larger than most hardness test dots I've seen.

I'd like to know how many collectors have Lugers with a dot next to a serial number on a part. Stevie has reported a third gun and it's a DWM too, although post-war. I hope ohers will examine their guns and report what they find.
