Updated through online information from Eric Cook.

Identified through on-line information from Eric Cook. -- The current instrument is the third pipe organ owned by St. Paul's. An English one manual instrument was purchased in 1837 and used until circa 1895 - it was the first pipe organ in Kittanning and Armstrong County, Pennsylvania. The second instrument was a 2 manual Odell, opus unknown that was sold in 1912. The current instrument was built new by the Tellers-Sommerhoff Company in 1913, when the current sanctuary was constructed (it is St. Paul's third building). The instrument was heavily modified and a new console was installed in 1961 by an unknown builder. The instrument was heavily damaged by water and was rebuilt using various pipes from various unknown instruments by William Siedel in 2006. The current console is believed to be the former console from the Ursaline Convent in Pittsburgh. The organ console and swell main chest were rebuilt by OSI, various other chests were rebuilt from the original instrument or other instruments by Mr. Siedel, the console has Peterson Memory Capture system and 100 levels of memory.
