Hello.
First of all, thank you for posting these photos. I saved three of them for my library.
If you will refer to your 2nd, 10th, and 17th photo you will notice a long gun/musket with a fish tail type butt stock. This gun is generally known as an Albanian Tanchika long gun. These guns were produced during the 18th and early 19th Century. Albania was an arms producing center in the Balkans primarily during this period.
Here is a photo of that gun. I have additional photos if you desire. Rick.
