Branson? Ultrasonic Welding, Swaging Or Staking Horn 51119DA2 New This item was purchased from a large business inventory reduction sale. This unit came in a box of items marked Branson. However, it does not have the brand name marked on it and so I am not able to verify the brand. I do not know the history of it. Many of the items from this purchase turned out to be new items that were kept as spares. This unit looks like a new spare. It measures about overall 5 1/16" long and the tube is about 5/8" in diameter. I am not able to test it. It only comes with what is shown in the pictures. S551-6 d rl fdk 81002208
