Parliament of Leaves

To start with, she has a name, and is called Charlotte. It just fits her.

Also, I got a response from someone at the Springfield Armoury National Park, which says lots of things.

This letter is in reference to your request for information concerning an
old percussion cap musket in your possession. Thanks for the images. They
came across clearly and reveal an interesting old rifle. It’s a rather long
rifle- certainly not a plains rifle, but more likely a Pennsylvania or Ohio
Valley rifle of the second quarter of the 19th Century. It has a very fine
piece of curly maple for a stock. The weapon used a late-period percussion
lock that seems a bit small for the gun. Perhaps it was a pistol lock. The
sideplate, barrel, & stock form all point to PA & OH areas. The ramrod
thimble is not, however, your typical rifle form [octagonal facets], but a
pistol or fowler example [cylindrical pipe]. The front sight is nicely
preserved as is the fore end cap. Interesting piece! Thanks for sending the
images.

So that's kind of keen!
