Another on ebay - looks to be in a poor condition and not sure if the photo shows a pile of pipes beside the console: http://www.ebay.co.uk/itm/231388631511?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
From the notes, it seems to be an ex-church organ which was re-erected in a house. It's not mentioned in NPOR as one of the organs in Callington (Masonic, Methodist and CofE). Nice little job for someone, somewhere....
