It is rare to find a modern firearm (last 50 years or so) that has NO markings at all. It is possible that those markings may have been removed from a modern firearm. Without some additional information, such as the type of firearm, we do not have enough information to offer a real answer.
The best way to find the manufacturer is to visit the store that the appliance was purchased from and give them the manufacturer code of the appliance. They should be able to provide contact information for the manufacturer.
