ATF Q&A: A & D Records

I have received a firearm on trade. It was commercially produced before 1968 and has no serial number. I must note the physical markings on the firearm in my records. What do I do in this case?

I started keeping my records of acquisition and disposition on loose sheets of paper. Can I three-hole punch the sheets and put them in a binder or get them spiral-bound and satisfy the bound book requirement?

What information should be placed in the A&D Record with respect to the heading "Manufacturer and/or Importer"?

What importer should be entered into the A&D book when the foreign manufacturer and the importer have the same company name?

What information should be entered into the A&D records in regards to the heading "Type" under "Description of Firearm."

If I have 2 separate FFLs at the same address, should I keep the inventory separate and use separate Acquisition and Disposition Records?

I have a question regarding entering a pistol in my A&D Book. The pistol in question is an FN 502, made by Umarex in Germany for FN America. Technically the manufacturer is Umarex and the importer is FN America, LLC. What is the proper way to enter this into my A&D book?

Where can I find the ATF's recent open letter to all FFLs providing firearm storage for individuals?

If change my personal FFL to my business FFL before my personal FFL expires so I will be able to transfer the guns into the new FFL what happens to my A/D books and 4473? If I do gunsmithing A/D book would need to get new books for everything I do in the new business name?
