The J.W. Walker organ installed in St. Andrew's Episcopal Church, Lawton, Oklahoma, was blessed at a service of Solemn Evensong on June 7, 1992. The organ was completely paid for at the time of its installation through pledges from church parishioners and the proceeds from a series of gourmet dinners sponsored by St. Andrew's. The gourmet dinners not only provided funds for the purchase and construction of the organ, but kept the project alive throughout the community. Generous monetary contributions from friends of St. Andrew's throughout Lawton/Fort Sill were made as a result of this community awareness. In February of 1990, the contract to construct the organ was signed with J. W. Walker & Sons Ltd. of Brandon, Suffolk England. Planning, design, and construction of the organ began and continued over the next twenty-five months.

The Clergy and the Vestry of St. Andrew's Episcopal Church consider the J. W. Walker organ not only an instrument to provide music for parish worship services, but also as a cultural resource for the Lawton/Fort Sill community and surrounding areas.
