It's a Reed & Prince!

Just another type of fastener (that is virtually obsolete)...

I'm not guessing any more screwdriver tips after what happened last time LOL

 The  Phillips  screwdriver  has  about  30-degree flukes and a blunt end, while the Reed and Prince has 45-degree flukes and a sharper, pointed end. The Phillips  screw  has  beveled  walls  between  the  slots;  the Reed  and  Prince,  straight,  pointed  walls.  In  addition, the Phillips screw slot is not as deep as the Reed and Prince  slot.
Screwdriver types-

FYI: The Reed & Prince appear as "Frearson" in the first two charts in Papaw's post above...

>The Reed & Prince appear as "Frearson"

Because the screw pattern was invented (and patented) by John Frearson of Birmingham , England, Patented in the US in 1884
