G,day davros,
I assume you are referring to the pin for the "duckbill" if so,from memory it is a 1lnch pin as used on tractor draw bars,they had a hole drilled in the lower end for a split pin or an"R"clip on a light chain or wire,as I said long time ago,close to 50 years, hope that is of some help,what is your planned tow vehicle? as any speed over 80kph with tyre pressure above 25 psi will give a tendency for an empty trailer to flip,saw this regularly on the Bruce Hwy when the Perentie first came into use,as S11a -S111 flat out at about 80k klicks
the pin had a loop welded on the top as a hand hold for wet muddy conditions or at night,remembering that the Army had 3 types of drivers,"drivers,drovers,and steering wheel attendants"
cheers
