In Stan Rogers "Make And Break Harbour" the one-lunger is presented as an icon of the olden days of inshore fishing, so I was astonished to come across this lyric (to the tune of "Jack Hinks" I thinks) which portrays the make-and-break engine as a new-fangled gimmick:

Ye fishermen free that go forth on the sea,
With engines of various makes;
This old jump-spark of mine I will take every time,
You can keep all your new makes-and-breaks.

From a song called The Six Horse-Power Coaker.

"Coaker" presumably refers to Sir William Ford Coaker, head of the Fishermen's Protective Union. Can anyone enlighten me as to why the engine got Sir William's name? Because both engine and man were small, loud, and hard-working? Because they were sold through the Fishermen's Union co-op stores? Or what?
