I have a feeling its an old traditional aid to splicing heavy cordage such as manila back before the modern ropes and mechanical aids came along.. a puller.
Some other old tools pictured below.

As part of a Spanish windlass perhaps??

The 104 mm is the cleat. Attach rope to be pulled with both hands.
