1887

In November 1887, it was resolved that the old organ was too small for the large church.  Contributions were $1000 over the $2200 needed for the new organ.

1888

Mr. Carl Barkhoff of Salem, Ohio builds an organ for the church in 1888.  Other bidders included Wm. Schuelke of Milwaukee and Jackson of Chester, Illinois.  The organ cost $3000 but was delivered for $2200.  It had 1566 pipes, with 5 mute show pipes in the front.  The organ consisted of two 58-key manuals and a 27-note pedalboard.  It was powered by a Ross water motor and dedicated on Tuesday, May 15, 1888.

1927

A new organ was dedicated on Sunday, November 13, 1927.  Built by the M. P. Möller Organ Company (Opus 4972?) of Hagerstown, Maryland, it contained 1402 speaking pipes in 20 ranks.  The reed pipes were described as being made of lead and a metal alloy, the string pipes were made of tin and lead, and flutes and other wood pipes were made of highest grade spruce, except the basses, which were made of pine.  The action was electro-pneumatic throughout.  The exterior finish of the organ was of dull solid walnut.  It is believed that some pipes from the 1888 organ were used in this instrument.  Organ specifications included 26 couplers, 24 adjustable combination pistons, 3 expression pedals, a tremulant for each manual, and a crescendo indicator.  The organ was powered by a 5 H. P. Kinetic Blower.  Professor Martin Lochner of Concordia, River Forest, Illinois played the evening dedicatory recital.

1960

A proposal from the United Organ Company of Milwaukee, Wisconsin to “modernize and repair” the organ was received in October, 1959.  It included a new electric console, tonal changes, cleaning, and partial releathering.  Work was done in the summer of 1960.  The total cost of the proposal was $10,450.  Seven sets of pipes were replaced, resulting in a new specification of 23 ranks and 1561 pipes.  The instrument was rededicated on Sunday, October 2, 1960 with Professor Paul Manz of Concordia, St. Paul, organist.

1972

It later became apparent that the organ was in need of complete rebuilding.  The Tellers Organ Company (Opus 1148) of Erie, Pennsylvania was chosen for that work.  The total cost of the project was $27,100.  The instrument's specification was increased to 24 ranks (35 stops) and 1748 pipes.  The rededication took place on Sunday, March 4, 1973, in special services played by Dennis Janko of Concordia Junior High, Hyattsville, Maryland.

1983

A contract was signed on April 11, 1983 with Peters, Weiland & Company of Milwaukee, Wisconsin for “enrichment” of the organ as outlined by Dr. Paul Bunjes.  Work included major reassortment of available ranks and the addition of 15 new ranks.  The total cost of the project was $44,427.

1986

On February 27, 1986, Dr. Bunjes delivered his final inspection report to Trinity.  It listed generally minor modifications, but also outlined a major problem with the pedal reed chorus.

1993

The organ console was replaced with a new mechanical action, 3 manual console by the Schlicker Organ Company of Buffalo, New York.  The cost was $38,500.  A new 2’ Waldflöte was also added to the Great division at this time, replacing the 2 foot Octave.

2003

A proposal for a new organ was presented to the Voters' Assembly for a cost of $627,000.  The congregation voted to delay signing a contract until at least 50% of the necessary funds have been raised.  Currently, $75,000 has been collected.
