I think Vose had tapered pins through the '20's; Henry F. Miller used them later also. We were given an abandoned square project that came with ca. 1970 new tapered pins from a supply house, though they are much too large for this instrument they will find their way into an appropriate piano. Maybe a screw maker could turn normal pins down, maybe a screw maker could sell new tapered pins - I'd buy them. Otherwise, I'll be recycling the sets I replace. They're easy to spot - pitch lowering with a nominally tight tapered pin by about 1/4 turn will make it very loose. Clark
