“Rijn en IJssel” ‘ (“Union of tugboat and pushboat owners Rhine and IJssel”),
based at Rotterdam. Rhine and IJssel, of course, are very important
rivers to the Dutch.
From my notes based on p. 73 of above book (this page is followed by
a dozen more dedicated to small or private owners related to Rijn en IJssel):
Founded at Arnhem 1927 as an interest group reacting to diminutive

The logo again, on a webpage
