I appreciate everyone indicating their gratitude. You are all most welcome. If you intend to build a Lehigh, there are a lot of details in these pictures that will start you down the right path. One of the most profound idiosyncracies regarding Lehigh rifles that amazed me, was their delicacy. They are fine and bird-like. The butt plates on some of them are less than four inches heel to toe. The barrels have only a gentle swamp, are very heavy for their calibre, and stock design. Many have from 1/8" - 3/16" of wood along the barrel channels, well below the centre line, and virtually flat from the roll to the ramrod groove.
That sight is cool. It has an insert set into the vertical part - Kuntz was pretty handy with saw and file. It is either an adjustable insert, or a replacement for an unsuccessful notch. There is nothing on the back side of the rear sight to lock it after adjustment, though. And it sits flush with the top, suggesting to me that it is a masterful and tedious repair. But it sure could be either, or whatever the owner wanted.
When I was examining this collection, I naturally shouldered all the pieces with shooting in mind. I did not shoulder a single rifle that I feel would have been awkward or uncomfortable to shoot. I have only built two Lehigh rifles, and I made sure that the drop at the comb especially, and at the heel, were adequate. Consequently, both rifles are easy and comfortable to shoot. Add to that that the bigger of the two bores was .45 calibre. If you mounted a .60 cal light octagon to round, as with one of those famous Herman Rupp runs, then you may have a bruiser.
One more observation...not all Lehigh rifles have an open ended nose piece. I have provided examples of both open and closed here.
I have some more pics to present, so I'd best get at it.
