These items were needed to offload goods [in bags] at the Docks and other locations.
The first Catalogue entry I can find is in 1888:
At that time only single and double Prong hooks were available with no speciality.
By 1897 there are more choices:
And more by 1909:
1921:
1928:
1938: A Malleable version of #3662 has been introduced as #3664
By 1959 the range has been whittled down to the Basics, no specialties.
And these 3 tools were themselves de-listed by December 1963
These tools may be difficult to find these days as they were probably discarded quite often, or lost. The following example may be either 3662 or 3664. I have no way of currently knowing the difference between SMALL and LARGE sizes.
