Hi Ibrahiim! Thank you very much for the photo. I will save it in my library. I notice the three containers on the top row which are the typical Ottoman brass containers to hold combustible cartridges. The bottom row showing a fourth container, powder flask, and yes - two small containers. They do all seem related. I'm now more convinced these small containers were used to carry pre-knapped flints. And maybe percussion caps if available.
Thanks again for your help. Most appreciated. Rick.
