The patent expired in the late 1980s, as I recall. Subsequent to that I
designed the Walter 190 grand using vertical hitch pins (though not of the
same type as used by Baldwin).

I've long considered the vertical hitchpin to provide a superior back string
termination and am still curious why other manufacturers have not at least
tried them. Other than Story & Clark I don't think anyone has.

Tradition, I guess. And probably a liberal amount of fear at rocking an
obviously sinking boat.
