Didn't Dwight do a request for these early 1920's lugers on whether they had sn on the firing pin 4 or 5 yrs ago?

Hold open, not sure... I would expect a number even if it started as a commercial but the markings on the right sound army / police all the way.
I would think to a average collector of lugers, the value would be lessened by the FP and HO not being numbered, so $950 to $1100 ? To someone who understands what Don said, IMO $1200-$1300 - the bluing is very good except for a few areas, so that might make it lower on the value to some?
