The "Sway Master" was/is most likely a brand of sway control
used to control trailer sway when towing. There are a lot of
different designs to do that, this one probably had a cable that
ran through the pulley wheels and was attached to some kind
of damping device and the hitch on the tow vehicle. I'm surprised
it's on such a small trailer as yours, but then any trailer can sway
if it is not designed right or correctly loaded, both of which are
not widely known. Check out the 'Design Resources' in the header
of this website for info on that.
