Just returned from my day trip (day1/2) to the Landis Museum in Lancaster.
Quite an eye-opener to see so many originals rifles in person, compared to my prior experience of simply trying to study these from profile photos.
Planned on staying about an hour (how long does it take to look at a few rifles?), and stayed for three. I kept going to my car and then would turn around and go back because I would have yet another question in my mind.
Interesting that although most of the featured rifles show the the sides of the forearm just below the midline of the barrel flats, some (a small few) are at midline, and one shows the barrel fairly well buried in the stock. This was the J. Dickert with the Irish registration number (originally a Revolutionary war trophy) of "DC1677" on the top barrel flat. It still tapers in the last couple of inches to reveal just less than 1/2 of the side flat at the nose cap only. It looked terrific!
You never see the off angle or oblique photos, as Acer posted above, in the books. It was a lot easier for me to visualize what is going on with the architecture of the wrist when looking from the butt forward. In some of the rifles this appears not to be just a "cylinder", but I think actually a cone with the diameter smallest at the wrist and flaring as it meets the rear of the lock panel.
I think I am getting a better idea of what is being described above. Remains to be seen if I can translate this to my current project. Maybe my next?
Thanks,
John
