Lugerdoc,
the whole upper is polished blue. What might look like missing blue is only a reflection. It has German Frankonia marks, and West German proof marks of which some are well hidden. No American import marks.
The Vopo star is underneath the takedown lever and is mostly covered by it. The overall condition is still pretty good, it has been refinished but not ground down too much and even a new Glock would cost me the same, without night sights
.
I will take this gun to the range this week end and try it out. I have several different reduced loads with different 124gr bullets.
