First of all , I am not expert in all areas . I have study antique weapons of this period . I have encounter fakes , which would good and very close . Now the say part of this they out make money. One must be very careful and you might be out of lot of money. One example of this , I was looking at Cook Brother rifle , the lock was right , but rest of the weapon was made in England . The parts will interchange . I handed back to the person , and kindly said no thank you , and told him the said news that was not real.
