Maybe this will help...
HHS Publication FDA 97-4179, Section 8 "Device Master Records"
Also attached is a copy of the Device Master Index for one of the products we manufacture. A lot of the documents are not in the Device Master Record, but are referenced in the DMR as to where the document is located (Document Control Office, Engineering Library, etc.). I have removed the name of the company and approval signatures from the attached.
Let me know if the attachment didn't come through.
