Organ has patents dating to late 1800's from "GEO F ROSCHE & CO", Chicago. Bellows in excellent shape - no obvious leakages. No missing or busted tricks - all practical - mainly in tune. A few of the Stops not working but quickly fixed. Have repair service manual and other paperwork for care and maintenance. Been in temp-controlled, smoke-free basement rec room for last couple of years. Sorry, we cannot provide. Money just simply.
