French silver maker's mark N.A.F. pre 1810

I have an older French salière with the maker’s mark of N.A.F. (exactly as shown on this website here: FRENCH SILVER MARKS - LES POINCONS DE L'ARGENT FRANCAIS: N ), but have never been able to find out who it is. Their site shows it as unknown. I’m attaching my attempt at photographing it, but I can’t zoom in as clearly as what’s shown in the above link. I’m also posting an image of the item in question. The silver mark is the Coq 1 for Paris pre 1810, and it has the guarantee mark with the man’s face and the 8 and 5 on each side of the face.
