The matchlock crowd, say about the time of Oliver Cromwell killing his king, used single charge wooden containers for their powder. Commonly suspended by cords from a crossbelt.

One term used for them in English was an Apostle, or really I guess in this context, apostle, all in lower case. No idea why it was called that, and the folks who could tell me are long dead.

Your setup reminds of that arrangement, exactly.
