Greetings.  There has been some discussion recently regarding a street
organ in a movie with the name "Mohlmann" on it.  According to the book
"From Music Boxes To Street Organs" Leon Mohlmann was an organ renter in
the Netherlands.  His stock of organs before and after WW II were mainly
Carl Frei.  He acquired even more Frei organs after the war.
