This instrument is a quintessential example of E.M. Skinner's medium sized instruments of the 1920's. This instrument was built in 1929 for St. Paul's Memorial Church, United Church of Christ, in Reading Pa. In 2009 Parkey moved the instrument, restored it, and installed it at St. Mark's Episcopal, Glendale Calif. Most importantly, the instrument was restored but not "improved".
