  • Robert Morton Muted Horn

    Does anyone have any construction details on this rare and coveted rank from the Robert Morton company, I would certainly would like to either add one or construct a rank.

    It is said that George Wright had the rank installed in his Studio Pipe Organs.

    Look for organs on the Internet that have the horn listed, and visit those organs, or research their construction.

    Way too many organs to list, but I do have 5 Allens:
    • MOS-2 Model 505-B / ADC-4300-DK / ADC-5400 / ADC-6000 (Symphony) / ADC-8000DKC
    • Lowrey Heritage (DSO-1)
    • 11 Pump Organs, 1 Pipe Organ & 7 Pianos

      Have not run across any of these horns in all my years of servicing theater pipe organs--there again, not may Robert Morton organs installed here in the south east. Since their factory was in Ca., I would check with organ builders on the west coast. Surely someone out there would know. Might even check Morton's patents to see if they were filed.

    Theater organ enthusiasts may be interested to know that there will be a free concert on the 4 manual Robert Morton organ at the Ohio Theater in Columbus, Ohio on Sunday, March 17 at 3 P.M. While a "muted horn" is not listed among the organ's 34 ranks, it does have a 16' Oboe Horn and an 8' English Horn.

          Sorry I am 2 years late but I can't help but get involved in this discussion. I take care of a 3/18 Wurlitzer in the Upstate NY area that does indeed have a Muted Horn. We even have it at 16'. The 16' portion is in storage but the 8' is installed and playing. Our 16' Tibia is Wurlitzer. In contrast to the Wurlitzer counterpart, the Muted Horn is slightly smaller in scale. The rank is quite nice and I even prefer it to the Wurlitzer. I cannot speak to the history of the rank or how/where we got it from but If you would like more info I can do my best to help out. Also curious if anyone has the statistics for how many of these ranks were produced and where they ended up.
