OK.
The company exists today in Switzerland, still in the business of producing pipe fittings and valves. Their marking remains +GF+.
Cinelli seat lugs, fork crowns, and bottom brackets were all castings produced by +GF+. (It is probably a coincidence but Cinelli's wife was Swiss.) Other Italian builders also used +GF+ cast bottom brackets and crowns in different patterns than those produced for Cinelli.
The Cinelli head lugs were conventional (formed from sheet metal with a welded seam) and quite possibly produced by Agrati..
I'm not aware of any other bicycle related "misc fitments" produced by +GF+.
