(:title {Xb-#817} Probable Factory hybrid owned by ORCHORSOL with Xb 29 ½” horn:) {Xb-#817} owned by ORCHORSOL which has what is believed to be a factory hybrid horn with early Xa narrow knuckle but later Xb 29 ½” final diameter. This appears to be a crossover instrument, perhaps using up previous stock. [Noted by [[http://forum.talkingmachine.info/viewtopic.php?f=11&t=22907&start=10|EMGER]]]
