Ernest Desmarais
1885

Updated through online information from John Speller. -- The second of these websites states that the organ was replaced by Casavant Op. 1635 of 1930. The accompanying photographs suggest that the neo-gothic casework may have been retained from the Desmarais instrument and may still be extant.

This entry describes an original installation of a new pipe organ.
