The Style 240 (3/14) Wurlitzer in the Riverside Theatre, Milwaukee, is the original installation with an added English (Post) Horn.  The theatre has recently reopened with the Pabst Theatre Foundation as the management company in charge of booking.

DTOS also maintains and presents programs on the McNeill Memorial Wurlitzer Organ located in the Racine Theatre Guild Playhouse, a 2/7 instrument that was installed at Racine's Capitol Theatre in 1926 as a 2/5.
