f your title 1 firearm has already been engraved by a Manufacturer, e.g. KRISS USA, with their information, a serial number, model, and a caliber, then the information from the engraving will be used in Box 4 and is considered to be the “Original Manufacturer” on the ATF Form 1 and the “Manufacturer” on the ATF 5320.23.
If your firearm is not currently engraved, then your information as the maker will go in Box 4 of the ATF Form 1 and the ATF 5320.23. The maker would be your name and address as an individual or the name and address of your gun trust, corporation or other legal entity, if you are applying with a legal entity.
