I remember that ad and am looking for a good copy of it. Dad and my Uncle Hugh both bought 20 gauges from that sale and I now own Uncle Hugh's. Hopefully I will inherit Dad's one day too.

Greg,
I will address your 5 questions.
1. Not all of the 500+ 16 barrels were added to guns by Kreighoff. Some (? how many) were sold aftermarket and were made available by various dealers. I remember Robin Hollow having 3 at an early Southern
2. All Kreighoff fitted barrels were #ed to the 20 gun.
3. All K barrels have the same pattern but each has an indivdual production number.
4. I have never seen a K barrel that was not 16 GA.
5. I have only seen the 3 choke combos you state. I have heard of SK1 and SK2 but never seen one.

Thanks Bob. What I was questioning in #4 is were all the Krieghoff’s 28” long? Or did they also make other lengths as well for this project?

If you or others that have a set of Krieghoff barrels stamped with the serial number to the gun they were fitted to, would you please post a pic showing it. TIA!

I have never seen or heard of anything other than 28".
Bob Jurewicz

Yes it has the SN stamped on the flats area of the Kreighoff barrel. Just verified.

I presume that thix is the P prefix gun you mentioned in the Reproduction chart thread 3 or 4 months ago. I find it odd that they stamped the barrels with a typical serial number format. I would think that if they were doing it, they would match the format of the frame. I have never encountered a P prefix gun. Could you post a frame picture of the SN?

All Parker Repro barrels, including the added K barrels are stamped in the same fashion: GAUGE FOLLOW BY THE SERIAL NUMBER
Here is a pic of the second K barrel in this set. Marked in same fashion as first shown in previous picture.

The Krieghoff people realized that the P was not intended to be a part of the numerical serial number, so they didn't include it. Or maybe the Repro people made the decision. No mystery there.
