We can research the serial number of your firearm and compile a factory letter of authenticity. Many customers are curious about this information, and find that it adds to the value of the firearm upon resale. Others have purchased, or are planning to purchase, a used firearm, and want to know its history. It is also nice to have for insurance purposes, or when passing the firearm to the next generation. The letter of authenticity is an official letter on Ed Brown Products letterhead, proving the authenticity of the serial number. It includes the date the firearm was originally shipped from the factory, and the location where the firearm was originally shipped. Any further information available about the model of firearm, its options, service record, and current replacement cost, will also be included. The letter is then signed by a member of the Brown family.
