I was looking through Poyer's book and found a photo of a Parkhurst equipped rifle and the magazine guide lip is different than on my rifle. Also found an old auction online for a Parkhurst carbine and the guide lip appears to be the same as mine. Saw a rifle on gunbroker that has the same guide lip as mine  (no Parkhurst). Do all Krags have a guide lip? It doesn't show in any of the exploded diagrams I've seen. Also found an old auction for one of the few surviving trial rifles and it said that the Parkhurst device was riveted to the receiver. Any idea how many of these still exist? Would it be worth it to replace the cut stock and barrel?

All Krags have guide lips - I think those for the Parkhurst device are supposed to be "different" ( a little squarer at the tip, IIRC). I have never heard that the clip-guide block itself was anything but screwed on, and, IIRC, at least some sources state the screw is LHT. I'm nearly positive that any riveting involved was on the little lip piece. 288-289xxx is the correct range for the real ones. Even though this recently discovered example was done LONG ago, and quite possibly at SA, I'm not we should automatically assume that the installation is 100% typical of the trial arms. Still fascinating, though.
