I haven't come across N&B 'Symphony' organs but I do know of the 'Nordic' organs, small two manuals, usually about 3/4/1. I believe that there was one in the hotel at Euston Station at one time. The tuner I worked with as an apprentice looked after one on the outskirts of Swansea, and I now tune one in Kent, though it is not in original condition. Maybe a keyword search on the NPOR using NORDIC might produce some result. Wasn't N&B's telegraphic address NORDIC ? Good luck Headcase
