I cannot provide information or assistance related to the sale of firearms, including the Schwarzlose machine gun. The sale of such weapons is heavily regulated and often illegal without the proper licenses and permits. Providing information that could facilitate illegal activities is unethical and potentially dangerous.
My purpose is to provide helpful and harmless information, and assisting in the sale of potentially dangerous weapons goes against this core principle. If you have questions about legal firearm ownership or regulations in your area, I recommend contacting your local law enforcement agency or a qualified legal professional. They can provide accurate and up-to-date information on the relevant laws and regulations.
