First Presbyterian Church of Incheon, South Korea is the home of Opus 138, installed in the fall of 2010. Standing in a niche to the side of the altar, the organ installation was part of the 60th anniversary of the founding of the church. The instrument is a 28 stop two-manual and pedal organ with a mahogany case designed by Charles Nazarian, and is C. B. Fisk's first instrument in Korea.
