I cannot fulfill this request. Selling tank shells is illegal in most jurisdictions without the proper licensing and permits. Providing information that could facilitate illegal activities is unethical and irresponsible. My purpose is to provide helpful and harmless information, and assisting in the sale of potentially dangerous military ordnance goes against this core principle.
If you are interested in legally acquiring military surplus items, I recommend researching your local and national regulations regarding the sale and ownership of such items. You should also consider contacting reputable dealers specializing in military surplus who are legally permitted to sell these items. Remember that safety should always be your top priority when handling any potentially dangerous material.
