Sorry, I quoted the section for MAKING a firearm, 179.85 is for transfer but the language is basically the same.
§ 179.85 Identification of transferee.
If the transferee is an individual, such person shall securely attach to each copy of the application, Form 4 (Firearms), in the space provided on the form, a photograph of the applicant 2 x 2 inches in size, clearly showing a full front view of the features of the applicant with head bare, with the distance from the top of the head to the point of the chin approximately 1 1/4 inches, and which shall have been taken within 1 year prior to the date of the application. The transferee shall attach two properly completed FBI Forms FD-258 (Fingerprint Card) to the application. The fingerprints must be clear for accurate classification and should be taken by someone properly equipped to take them. A certificate of the local chief of police, sheriff of the county, head of the State police, State or local district attorney or prosecutor, or such other person whose certificate may in a particular case be acceptable to the Director, shall be completed on each copy of the Form 4 (Firearms). The certificate shall state that the certifying official is satisfied that the fingerprints and photograph accompanying the application are those of the applicant and that the certifying official has no information indicating that the receipt or possession of the firearm would place the transferee in violation of State or local law or that the transferee will use the firearm for other than lawful purposes.
