I collect cartridges and documents related to these types of firearms and conduct research on these topics, furthering my understanding and knowledge of these historical firearms and their place in the evolution of firearms technology. My collection and research reflect my dedication to preserving and understanding the history and technical innovations of these early firearms systems.
